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

The formula for converting watt seconds to kilowatt hours is: kWh = Ws × 0.0000002777778. To calculate the watt second value in kilowatt hours first substitute the watt second value into the preceding formula, and then perform 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

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

Example Conversion

Let's take a look at an example. The step-by-step process to convert 6 watt seconds to kilowatt hours is:

Understand the conversion formula: kWh = Ws × 0.0000002777778
Substitute the required value. In this case we substitute 6 for Ws so the formula becomes: kWh = 6 × 0.0000002777778
Calculate the result using the provided values. In our example the result is: 6 × 0.0000002777778 = 0.0000016666668 kWh

In summary, 6 watt seconds is equal to 0.0000016666668 kilowatt hours.

Converting kilowatt hours to watt seconds

In order to convert the other way around i.e. kilowatt hours to watt seconds, you would use the following formula: Ws = kWh × 3600000. To convert kilowatt hours to watt seconds first substitute the kilowatt hour value into the above formula, and then execute 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

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

Conversion Unit Definitions

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.

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.
