Newton's Law of Cooling Calculator

Time Difference:
Surrounding Temperature:
Initial Temperature:
Coeffient Constant:
Final temperature:

Newton's law of cooling is sometimes called "Convection-cooling" is independent of the temperature difference between object and environment.

Newton's Law of Cooling Formula

T2 = T0 + (T1 - T0) * e(-k * Δt)


k: Constant to be found

Δt: Time difference of T2 and T1

T1: Initial Temperature

T2: Final Temperature

T0: Constant Temperature of the surroundings

For example, when Time is 9, surrounding temperature is 20, initial temperature is 30, Core temperature is 32, then Temperature of the object at time t T(t) is 72. provides you helpful and handy calculator resources.
