Formula and methodology
Formula: Remaining amount=initial amount×0.5^(elapsed time/half-life).
This is a simple decay model. It does not estimate a safe intake, individual metabolism, impairment, or medical effect.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Initial amount — minimum 0; maximum 100000
- Half-life in hours — minimum 1.0E-6; maximum 1000
- Elapsed hours — minimum 0; maximum 10000
Worked example
| Input | Value |
|---|---|
| Initial amount | 200 |
| Half-life in hours | 5 |
| Elapsed hours | 8 |
Remaining amount ≈65.9754 mg; eliminated ≈134.0246 mg.
Assumptions and limits
- The initial amount and half-life use the same amount and time context.
- One constant half-life and first-order decay are assumed.
- Absorption, repeated doses, food, genetics, pregnancy, medicines, sleep, and individual response are not modeled.
