# Newton’s Law of Cooling Calculator

Enter the initial temperature, ambient temperature, cooling coefficient, and total time into the calculator. Using Newton’s law of cooling, the calculator will determine the final temperature.

## Newton’s Law of Cooling Formula

The following equation can be used to calculate the temperature of a substance after a certain time and cooling rate.

Tf = Ta + (Ti – Ta * exp(- c * t)

• Where Tf is the final temperature
• Ta is the ambient temperature
• Ti is the initial temperature
• c is the cooling coefficient
• t is the total time

How to calculate Newton’s Law of Cooling

1. First, measure the ambient temperature

This will be the temperature of the air surrounding the object.

2. Next, measure the initial temperature

This will be the initial temperature of the object or substance being analyzed.

3. Determine the cooling coefficient

Calculate or measure the cooling coefficient using the material properties of the substance and the surface area.

4. Calculate the final temperature

Enter the time period you wish to analyze along with the information from steps 1-3 into the formula above to calculate the final temperature.
