How to Convert Joule to Watt-hour

Conversion Formula

1 j = 2.78e-4 wh

Step-by-Step Explanation

  1. Understand the base relationship:
    1 Joule = 1.000 joules
    1 Watt-hour = 3.60k joules
  2. Establish the conversion factor:
    1 j = (1.000 J) / (3.60k J/wh) = 2.78e-4 wh
  3. Apply the conversion:
    Multiply the value in j by 2.78e-4 to get the equivalent in wh

Example Conversion

Convert 5 j to wh:

5 j × 2.78e-4 = 0.001389 wh
