Enter the emitted radiation and the blocked radiation into the Calculator. The calculator will evaluate the Emissivity.

## Emissivity Formula

E = ER / BR

Variables:

• E is the Emissivity ()
• ER is the emitted radiation
• BR is the blocked radiation

## How to Calculate Emissivity?

The following steps outline how to calculate the Emissivity.

• First, determine the emitted radiation.
• Next, determine the blocked radiation.
• Next, gather the formula from above = E = ER / BR.
• Finally, calculate the Emissivity.
• After inserting the variables and calculating the result, check your answer with the calculator above.
