## How to convert watt hours to watt seconds (Wh to Ws)

The formula for converting watt hours to watt seconds is: Ws = Wh × 3600. To calculate the watt hour value in watt seconds first substitute the watt hour value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 watt hour in watt seconds we follow these steps:

Ws = Wh × 3600

Ws = 1 × 3600

Ws = 3600

In other words, 1 watt hour is equal to 3600 watt seconds.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 2 watt hours to watt seconds is:

1. Understand the conversion formula: Ws = Wh × 3600
2. Substitute the required value. In this case we substitute 2 for Wh so the formula becomes: Ws = 2 × 3600
3. Calculate the result using the provided values. In our example the result is: 2 × 3600 = 7200 Ws

In summary, 2 watt hours is equal to 7200 watt seconds.

## Converting watt seconds to watt hours

In order to convert the other way around i.e. watt seconds to watt hours, you would use the following formula: Wh = Ws × 0.0002777778. To convert watt seconds to watt 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 watt hours we follow these steps:

Wh = Ws × 0.0002777778

Wh = 1 × 0.0002777778

Wh = 0.0002777778

Or in other words, 1 watt second is equal to 0.0002777778 watt hours.

## Conversion Unit Definitions

### What is a Watt Hour?

A watt-hour (Wh) is a unit of energy commonly used in the context of electricity consumption and production. It represents the amount of energy consumed or produced by a one-watt electrical device operating for one hour.
Mathematically, 1 watt-hour is equal to the energy used by a one-watt device over a period of one hour. It can also be expressed as: 1 Wh = 1 watt × 1 hour.
Watt-hours are used to measure the total energy usage of appliances, buildings, or entire power grids over a specific period of time. For example, if a 100-watt light bulb is turned on for 10 hours, it consumes 1,000 watt-hours or 1 kilowatt-hour (kWh) of electricity (since 1 kWh = 1,000 Wh).
Watt-hours are widely used by utility companies to measure and bill for electricity consumption by households and businesses.

### 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.
