1 J = 2.78e-7 kWh

Full precision:2.78e-7 kWh

Step-by-Step Solution

To convert 1 joules to kilowatt-hours, we divide by 3600000 because one kilowatt-hour equals exactly 3600000 joules.

1 kilowatt-hour = 3600000 joules

Since there are 3600000 joules in every kilowatt-hour, we divide our value by this factor:

1 ÷ 3600000 = 2.78e-7 kilowatt-hours

So 1 joules = 2.78e-7 kilowatt-hours.

✓Quick check: 2.78e-7 × 3600000 = 1 joules

How to Convert Joules to Kilowatt-hours

To convert joules to kilowatt-hours, divide the value by 3600000.

Kilowatt-hours = Joules ÷ 3600000

1 kilowatt-hour = 3600000 joules

Tip: To convert kilowatt-hours back to joules, multiply by 3600000.

Example 1: 1 J = 2.78e-7 kWh
1 ÷ 3600000 = 2.78e-7

Example 2: 5 J = 0 kWh
5 ÷ 3600000 = 0

Example 3: 10 J = 0 kWh
10 ÷ 3600000 = 0
