Half-Life Calculator

Result
Half-Life: - hours


A half-life calculator helps determine the time it takes for half of a radioactive substance to decay or for a substance in a chemical reaction to reduce by 50% of its original quantity. This tool is widely used in physics, chemistry, environmental studies, and pharmacology to analyze decay processes or drug clearance times.

How to Use the Half-Life Calculator

For Radioactive Decay

  1. Enter the initial quantity of the substance.
  2. Provide the remaining quantity after a specific time.
  3. Input the elapsed time.
  4. The calculator computes the half-life using the decay formula:
    Half-Life (T₁/₂) = (t × log(2)) / log(Q₀ / Q)
    Where:
    • Q₀ = Initial quantity
    • Q = Remaining quantity
    • t = Elapsed time

For Drug Clearance

  1. Input the initial drug concentration in the body.
  2. Provide the remaining concentration after a known time.
  3. Calculate to find the drug's half-life.
