half-life calculator

click on the calculated volume or calculated temperature that you want to calculate.

`T_(1/2)=[T×Log2]/[Log[(AmtB)/(AmtE)]] `
`AmtE=[AmtB]/2^n `
`n=T/T_(1/2) `
T1/2 = Half Life
T = Elapsed Time
AmtB = Beginning Amount

about the half-life calculator

the half-life calculator is used to calculate the half-life of exponential decay.

half-life is the time it takes for decaying matter to reduce by half. it is commonly used to describe quantities that undergo exponential decay (such as radioactive decay), where the half-life remains constant throughout the lifetime of the decay, and is a characteristic unit (the natural unit of scale) for exponential decay equations. however, half-life can also be defined as a non-exponential decay process, although in these cases the half-life changes throughout the decay process.
