sin⁻¹(width / length)
Time of Death Estimator
Estimate postmortem interval from body temperature using algor mortis.
(98.6°F − body temp) ÷ 1.5 = hours since death (approx.)
ADH Calculator
Calculate accumulated degree hours for blowfly development timing.
ADH = avg temp (°C) × hours elapsed
DNA Profile Probability
Understand random match probability for STR profiles.
Product of allele frequencies in a population
