Enter the total watts and the total time (hrs) into the Calculator. The calculator will evaluate the Watt Time. 

Watt Time Formula

WT = W * T


  • WT is the Watt Time (watt-hours)
  • W is the total watts
  • T is the total time (hrs)

To calculate Watt Time, multiply the total watts by the total time.

How to Calculate Watt Time?

The following steps outline how to calculate the Watt Time.

  1. First, determine the total watts. 
  2. Next, determine the total time (hrs). 
  3. Next, gather the formula from above = WT = W * T.
  4. Finally, calculate the Watt Time.
  5. 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.

total watts = 30

total time (hrs) = 10
