sci.time-of-death-algor-mortis Calculator
Calculates estimated time of death from body core temperature using Newton's law of cooling: T_body = T_ambient + (T_initial − T_ambient) × exp(−kt). Algor mortis rate ≈ 1.0–1.5 °C/hour — accuracy degrades beyond 12 hours as core temperature approaches ambient.
Inputs
Body Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Ambient Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Body Weight Kg
Body or object weight. For health calculators, usually in kg or lbs.
Results
estimated hours since death
The result expressed in hours. Divide by 24 to convert to days.
temperature drop
The value at the specified point or condition.
cooling rate
The value at the specified point or condition.
ambient temperature
The value at the specified point or condition.
Henssge formula
The specific form or variant of the result.
error margin
The difference between the computed result and the exact or true value — a measure of approximation accuracy.
