Free Half-Life of a Substance Calculator - Given a half-life (h) of a substance at time t, this determines the new substance size at time t_{n}, otherwise known as decay.

This calculator has 4 inputs.

This calculator has 4 inputs.

Δ = t_{n} - t

Number of half lives = Δ/half life

Half Life Remaining = 1/2 * Prior Amount
