How to convert kilowatt hours to watt seconds (kWh to Ws)

The formula for converting kilowatt hours to watt seconds is: Ws = kWh × 3600000. To calculate the kilowatt hour value in watt seconds first substitute the kilowatt hour value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 kilowatt hour in watt seconds we follow these steps:

Ws = kWh × 3600000

Ws = 1 × 3600000

Ws = 3600000

In other words, 1 kilowatt hour is equal to 3600000 watt seconds.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 5 kilowatt hours to watt seconds is:

Understand the conversion formula: Ws = kWh × 3600000
Substitute the required value. In this case we substitute 5 for kWh so the formula becomes: Ws = 5 × 3600000
Calculate the result using the provided values. In our example the result is: 5 × 3600000 = 18000000 Ws

In summary, 5 kilowatt hours is equal to 18000000 watt seconds.

Converting watt seconds to kilowatt hours

In order to convert the other way around i.e. watt seconds to kilowatt hours, you would use the following formula: kWh = Ws × 0.0000002777778. To convert watt seconds to kilowatt hours first substitute the watt second value into the above formula, and then execute the calculation. If we wanted to calculate 1 watt second in kilowatt hours we follow these steps:

kWh = Ws × 0.0000002777778

kWh = 1 × 0.0000002777778

kWh = 0.0000002777778

Or in other words, 1 watt second is equal to 0.0000002777778 kilowatt hours.

Conversion Unit Definitions

What is a Kilowatt Hour?

A kilowatt-hour (kWh) is a unit of energy commonly used for measuring electricity consumption. It represents one kilowatt (kW) of power used continuously for one hour. In other words, it is a measure of energy equivalent to 1,000 watt-hours or 3.6 million joules.

Mathematically, 1 kilowatt-hour is equal to: 1 kWh = 1 kilowatt × 1 hour = 1,000 watts × 1 hour.

Kilowatt-hours are the standard billing units used by electric utilities for measuring the amount of energy consumed by residential, commercial, and industrial customers over time. For example, if you use a 1,000-watt (or 1 kilowatt) appliance for one hour, you will have consumed 1 kilowatt-hour of electricity. Utility bills often display the total energy consumption in kilowatt-hours, and consumers are charged based on the number of kilowatt-hours they use.

What is a Watt Second?

A watt-second (Ws), also known as a joule (J), is a unit of energy in the International System of Units (SI). It represents one watt of power expended for one second. Mathematically, it can be defined as: 1 watt-second (Ws) = 1 watt (W) × 1second (s) = 1 joule (J).

Watt-seconds are used to measure the energy consumed or produced by electronic devices or electrical systems in a very short amount of time. For example, the energy released by a camera flash, the energy stored in capacitors, or the energy consumed by a small electronic circuit during its operation can be measured in watt-seconds.

In practical terms, a watt-second is a relatively small unit of energy. To provide some context, 1 watt-second is equivalent to the energy required to power a 1-watt device for 1 second.
