Watt-seconds to Kilowatt-hours Conversion
Enter the energy in watt-seconds below to get the value converted to kilowatt-hours.
How to Convert Watt-seconds to Kilowatt-hours
To convert a watt-second measurement to a kilowatt-hour measurement, divide the energy by the conversion ratio. One kilowatt-hour is equal to 3,600,000 watt-seconds, so use this simple formula to convert:
The energy in kilowatt-hours is equal to the watt-seconds divided by 3,600,000.
Watt-seconds and kilowatt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.
Watt-seconds are usually abbreviated as Ws, although the formally adopted expression is W·s. The abbreviation W s is also sometimes used. For example, 1 watt-second can be written as 1 Ws, 1 W·s, or 1 W s.
In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.
A kilowatt-hour is a measure of electrical energy equal to one kilowatt, or 1,000 watts, of power over a one hour period. Kilowatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.
Kilowatt-hours are usually abbreviated as kWh, although the formally adopted expression is kW·h. The abbreviation kW h is also sometimes used. For example, 1 kilowatt-hour can be written as 1 kWh, 1 kW·h, or 1 kW h.
