Use this caffeine half-life calculator to determine how long it will take for the caffeine in your system to reduce to half its original amount.

## Caffeine Half-Life Calculator Explained

The caffeine half-life calculator is designed to estimate the time it takes for the caffeine amount in your body to reduce to half of its original concentration. The calculation is based on the amount of caffeine you consumed and your body weight.

### How to Use the Calculator

- Enter the amount of caffeine in milligrams (mg) you have consumed.
- Enter your body weight in kilograms (kg).
- Click on the “Calculate” button to get the estimate.

### How It Calculates the Results

The calculator uses a standard formula which involves the average half-life of caffeine (5.7 hours) and applies it to the entered body weight and caffeine amount. Please note that the calculation assumes a basic metabolism rate and does not take into account personal metabolism variations.

### Limitations of the Calculator

While the caffeine half-life calculator provides an estimate based on averages, individual results may vary due to factors such as age, medical conditions, and the efficiency of the liver enzymes responsible for metabolizing caffeine. Always consult a medical professional for health-related advice specific to your situation.
