Enter the total wattage (watts) and the total area (m^2) into the Watt Density Calculator. The calculator will evaluate and display the Watt Density.

## Watt Density Formula

The following formula is used to calculate the Watt Density.

WD = TW / TA
• Where WD is the Watt Density (watts/m^2)
• TW is the total wattage (watts)
• TA is the total area (m^2)

To calculate the watt density, divide the total wattage by the total area.

## How to Calculate Watt Density?

The following example problems outline how to calculate Watt Density.

Example Problem #1:

1. First, determine the total wattage (watts).
1. The total wattage (watts) is given as: 50.
2. Next, determine the total area (m^2).
1. The total area (m^2) is provided as: 2.
3. Finally, calculate the Watt Density using the equation above:

WD = TW / TA

The values given above are inserted into the equation below:

WD = 50 / 2 = 25 (watts/m^2)

Example Problem #2:

For this problem, the variables needed are provided below:

total wattage (watts) = 260

total area (m^2) = 3

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

WD = TW / TA = ?
