Joules to Watt-Hours Converter
Joules to Watt-Hours Conversion
To convert Joules (J) to Watt-hours (Wh), use the formula:
Conversion Formula
The relationship between joules and watt-hours can be expressed as:
Wh = J ÷ 3600Where:
- Wh = Watt-hours
- J = Joules
Example Calculation
If you have an energy amount of 7200 J, the calculation would be:
Wh = 7200 J ÷ 3600 = 2 WhWhat is a Joule (J)?
A joule (J) is a unit of energy in the International System of Units (SI). It is defined as the amount of energy transferred when a force of one newton is applied over a distance of one meter. It can also be defined as the energy used when one watt of power is applied for one second.
What is a Watt-hour (Wh)?
A watt-hour (Wh) is a unit of energy that measures the amount of work done or energy consumed over time. It represents the energy used when one watt of power is consumed for one hour.
The Simple Math Behind the Conversion
To convert joules to watt-hours, you divide the joules by 3600, since there are 3600 seconds in an hour. Here’s a breakdown:
- 3600 J = 1 Wh
- 7200 J = 2 Wh
- 18000 J = 5 Wh
