Enter the final temperature and the change in temperature into the Calculator. The calculator will evaluate the Initial Temperature.

- Final Temperature Calculator
- CTE (Coefficient of Thermal Expansion) Calculator
- Resistance to Temperature Calculator

## Initial Temperature Formula

IT = FT - dT

Variables:

- IT is the Initial Temperature (C or F)
- FT (C or F) is the final temperature
- dT (C or F) is the change in temperature

To calculate Initial Temperature, subtract the change in temperature from the final temperature.

## How to Calculate Initial Temperature?

The following steps outline how to calculate the Initial Temperature.

- First, determine the final temperature.
- Next, determine the change in temperature.
- Next, gather the formula from above = IT = FT – dT.
- Finally, calculate the Initial Temperature.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

final temperature = 30

change in temperature = 10
