What is a Watts to kWh Converter?

The Watts to kWh Calculator is a tool used to convert electrical power consumption from watts into kilowatt-hours. It is absolutely necessary to perform the conversion, which leads to the calculation of energy use for an appliance or any device that consumes electricity over a certain period of time. In turn, the conversion will be helping you understand how much electricity is consumed in terms of kilowatt-hours, which is indeed the standard unit utilized by an electricity provider to bill their consumers on account of their usage.

With the watts-to-kWh converter, you can have energy in kWh out of Watts and time in hours. This topic is very important for accounting in the aspect of costing electricity consumption and energy efficiency.

You can concert watt to kWh by using the following formulas.

Watts to kWh Conversion

Formula: Watts to kWh Conversion

To convert watts to kilowatt-hours (kWh), you use the following formula:

\[ \text{kWh} = \frac{\text{Watts} \times \text{Time (in hours)}}{1000} \]

Where:

  • \( \text{kWh} \) = Energy consumption in kilowatt-hours
  • \( \text{Watts} \) = Power consumption in watts
  • \( \text{Time} \) = Duration of usage in hours

Example Calculation

If you have a 500-watt appliance running for 3 hours:

\[ \text{kWh} = \frac{500 \times 3}{1000} = 1.5 \, \text{kWh} \]

This means the appliance would consume 1.5 kilowatt-hours of electricity during the 3 hours.

What is Watts and kWh?

Watts (W)

The watt, or W, is the unit of electrical power, or the amount of energy consumed or produced. In other words, it simply measures the quantity of energy that an appliance uses or produces within a second. One watt measures one joule of energy per second. For example, using a light bulb with a rating of 100 watts means that in a second, it consumes an amount of energy equivalent to 100 joules.

Kilowatt-hour (kWh)

The kilowatt-hour is a unit of energy that, in terms of time, measures the amount of energy utilized. It refers to the amount of energy used by an appliance rated at 1 kW running for one hour. For example, when an appliance rated at 1,000 watts runs for an hour, then it is said to have consumed 1 kWh of energy.
