Safe driving requires mind and body coordination and alertness to assess situations on the road. It would be best if you had quick reflexes to avoid sudden dangers that may come up while driving. In contrast, alcohol consumption impairs the senses, perception, and motor functions necessary for safe driving. Despite this, many people continue to drive under the influence of alcohol. Impaired driving is one of Australia’s leading causes of road accidents and incidents. Also, drink driving is a criminal offence. Individuals can face legal consequences if they measure a Blood Alcohol Content (BAC) of 0.05% or higher. Therefore, more people use a blood alcohol calculator in Australia to avoid drink driving charges. 

Your impairment or intoxication level directly depends on the alcohol amount you consumed. The BAC level is the percentage of alcohol in your system. Therefore, the more you drink alcohol, the higher your BAC level is. Understanding how alcohol affects your body is a great way to control your BAC and alcohol consumption. Thus, you can use a blood alcohol calculator to help you monitor your alcohol level in Australia. Also, if you are looking for a blood alcohol calculator, the BACtrack personal breathalysers from Breathalysers Australia are the best option. A breathalyser device efficiently examines alcohol in the sample breath through sensors to estimate the BAC level. Additionally, BACtrack breathalysers use advanced fuel cell sensors to determine your intoxication quickly and accurately.

Blood Alcohol Calculator in Australia: What Is BAC?  

Alcohol intoxication, sometimes known as drunkenness, is measured by Blood Alcohol Concentration (BAC). It is usually represented as a ratio of alcohol to blood volume. When someone consumes alcohol, it enters their bloodstream and travels to their organs. In an average healthy person, blood circulates through the body in 90 seconds, which means they can experience the effects of alcohol 15 to 45 minutes after their first drink. Blood alcohol calculators in Australia show the measurement as BAC%, and the legal limit is 0.05%. If your test is equal to or above that limit, you can face legal consequences once apprehended.  

In addition, the liver can process one standard drink in an hour. Age, weight, gender, personal metabolism, and the amount of food consumed all influence how quickly the body absorbs alcohol. The BAC of a person drops by 0.015 per hour or 0.015 g/100mL/hour on average. Time, sleep, food, or other means will not be able to speed up this procedure. No matter how hard a person tries, they cannot get alcohol out of their system once it is in their body. Blood alcohol calculators can help you monitor your BAC until you are sober. The timeframe for detecting alcohol in a person’s system depends on the method used to test it: 

• Blood Test: 6 to 12 hours  
• Breath Test: 12 to 24 hours  
• Saliva Test: 12 to 24 hours  
• Urine Test: 12 to 24 hours  
• Hair Test: 90 Days 

Using an Online Blood Alcohol Calculator in Australia to Determine the BAC

A popular way of computing the BAC of an individual is using an online blood alcohol calculator in Australia. These are websites on which a person can enter details (factors that affect the BAC levels) and then automatically compute for the BAC. It is based on the Widmark Formula, which states that “one’s BAC is equal to the number of ounces of alcohol consumed, multiplied by a constant (3.75 for men and 4.7 for women) and then divided by that person’s weight”. Factors to enter in most online calculators are:

• gender
• body weight
• time since the first drink
• type of alcohol
• amount and volume of alcohol consumed
• percent of alcohol by volume of the drink

However, it is vital to note that online blood alcohol calculators are only estimates, and results are never 100% accurate. Hence, individuals should not rely on these, especially when considering driving. This is because alcohol has varying effects on individuals. Moreover, there are other factors that affect the BAC level that online calculators cannot account for, such as:

• age
• body type
• food intake
• metabolism rate
• medications
• body fat and muscle percentage
• fitness level
• the speed at which alcohol was consumed

Therefore, BAC results from an online blood alcohol calculator can be inaccurate and unreliable. A person relying on these guess estimates may find themselves attaining a drink driving charge or risking the safety of themselves or others. Thus, individuals should have a more reliable method for determining the BAC.

Blood Alcohol Calculator in Australia: Breathalysers

Multiple testing methods are available to detect the exact BAC of individuals. Blood, saliva, urine, and hair tests are among them. However, these testing methods require a laboratory to process the samples to determine the exact BAC levels. Thus, it makes them time-consuming and impractical for the average person. On the other hand, breath tests using a breathalyser are the fastest and also least invasive procedure. Using a breathalyser as a blood alcohol calculator in Australia is the most practical and cost-efficient method. Individuals would only need to provide an adequate breath sample by blowing into the device’s sterilised mouthpiece. Furthermore, the process by which the device produces a corresponding BAC value would depend on the sensor type:

1. Semiconductor sensor – the device uses a tin-oxide substance to heat a steel mesh film with a heater coil. Then, when a breath sample containing alcohol hits the heated film, it charges the resistance. The device can provide a BAC value from the change in sensor resistances.
2. Fuel cell sensor – the device oxidises alcohol in the breath by undergoing an electrochemical process. Then, the resulting chemical reaction will produce small electrical charges based on the volume of alcohol relative to the amount in the blood and convert it into a BAC value. 

Particularly, Breathalysers Australia offers breathalysers as blood alcohol calculators specifically designed for personal use. These devices are highly accurate and can provide precise BAC results at a touch of a button in just 10 to 15 seconds.

Blood Alcohol Calculator in Australia: BAC Levels and their Effects  

The degree of impairment induced by alcohol consumption varies depending on the BAC. At levels between 0.001 to 0.029%, impairments range from mild effects that can only be identified with sophisticated tests to issues with focus, reflexes, motor control, and more, with a substantial risk of death at 0.50% or more. The blood alcohol calculators in Australia provide accurate BAC levels using BACtrack breathalysers. These levels have different effects on the body. Here is a quick guide to the effects:  

• 0.001 to 0.029 BAC% – mild effects such as an altered mood, a feeling of relaxation and a slight loss of judgement (can only be identified with sophisticated tests).
• 0.030 to 0.059 BAC% – reduced concentration and lowered alertness and inhibition.
• 0.060 to 0.099 BAC% – impairment in judgement, reasoning, depth perception, peripheral vision, glare recovery and muscle coordination.
• 0.100 to 0.199 BAC% – low reflexes, reaction time, gross motor control, staggering, slurred speech, slowed thinking and can have temporary erectile dysfunction.
• 0.200 to 0.299 BAC% – causes severe motor impairment, confusion, vomiting, drowsiness, loss of consciousness and memory blackout.
• 0.300 to 0.399 BAC% – a person can have bladder dysfunction, breathing dysequilibrium, faster heart rate and a high possibility of having alcohol poisoning.
• 0.400 to 0.500 BAC% – has breathing impairment, faster heart rate and positional alcohol nystagmus  
• BAC% over 0.500 – highly dangerous and possibly fatal (risk of coma and fatality due to respiratory arrest).

Why Use a Breathalyser as a Blood Alcohol Calculator in Australia?  

Alcohol effects work differently among individuals. For example, you may feel fine and in control after consuming one standard drink while others already feel intoxicated. Therefore, determining the BAC based on the number of standard drinks is inaccurate and unreliable. Using a breathalyser as a blood alcohol calculator in Australia before driving helps reduce the likelihood of getting into an accident. Thus, it facilitates good road safety. Notably, using BACtrack breathalysers from Breathalysers Australia can promote healthier practices. Breathalysers like BACtrack can help with BAC tracking and consumption monitoring, which can help increase awareness. 

In addition, Australia is a country that takes road safety seriously. Around 1,200 people have perished, and about 40,000 are seriously injured each year on Australian roads. Accordingly, alcohol-related driving accidents are a leading cause of these mortality rates. Consequently, Australia has very strict drink driving laws in order to promote road safety. This adds to the reasons why you should own a personal blood alcohol calculator.

Blood Alcohol Calculator Australia: Drink Driving Laws

Driving Under the Influence (DUI) of alcohol, more commonly known as drink driving, is a serious offence in Australia. Drivers on Australian roads must stay within the alcohol driving limits. The alcohol driving limit would be based on what type of license a person holds. Moreover, Australia has a national legal limit set. However, each State or territory also has their own set of alcohol-driving limits and corresponding penalties. In line with this, owning a personal blood alcohol calculator in Australia, like a BACtrack breathalyser from Breathalysers Australia, can help individuals monitor their alcohol intake to stay within legal limits.

National Alcohol Driving Limits

• Zero BAC – zero alcohol level applies to drivers with a learner, provisional 1 and 2 permits. New drivers are developing their driving skills and must maintain a speed limit of 100 km/hr or below. In addition, visiting drivers or drivers holding an overseas license must adhere to a zero BAC limit. Zero BAC limits mean that there must not be any alcohol content in the system while driving. 
• Under 0.02 BAC – this BAC limit applies to drivers of gross vehicle mass (GVM) or vehicle units exceeding 13.9 tonnes. Likewise, drivers carrying dangerous goods and public utility vehicles such as taxis and buses must keep below 0.02 BAC.
