How to convert btus to kilowatt hours (Btu to kWh)

The formula for converting btus to kilowatt hours is: kWh = Btu × 0.00029329722222222. To calculate the btu value in kilowatt hours first substitute the btu value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 btu in kilowatt hours we follow these steps:

kWh = Btu × 0.00029329722222222

kWh = 1 × 0.00029329722222222

kWh = 0.00029329722222222

In other words, 1 btu is equal to 0.00029329722222222 kilowatt hours.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 7 btus to kilowatt hours is:

  1. Understand the conversion formula: kWh = Btu × 0.00029329722222222
  2. Substitute the required value. In this case we substitute 7 for Btu so the formula becomes: kWh = 7 × 0.00029329722222222
  3. Calculate the result using the provided values. In our example the result is: 7 × 0.00029329722222222 = 0.00205308055555554 kWh

In summary, 7 btus is equal to 0.00205308055555554 kilowatt hours.

Converting kilowatt hours to btus

In order to convert the other way around i.e. kilowatt hours to btus, you would use the following formula: Btu = kWh × 3414.4259497. To convert kilowatt hours to btus first substitute the kilowatt hour value into the above formula, and then execute the calculation. If we wanted to calculate 1 kilowatt hour in btus we follow these steps:

Btu = kWh × 3414.4259497

Btu = 1 × 3414.4259497

Btu = 3414.4259497

Or in other words, 1 kilowatt hour is equal to 3414.4259497 btus.

Conversion Unit Definitions

What is a Btu?

BTU, or British Thermal Unit, is a unit of heat energy commonly used in the United States and some other countries. One BTU is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit at a constant pressure.
In SI units, one BTU is approximately equal to 1,055 joules. It is often used in the context of heating, air conditioning, and energy-related applications, especially in the United States. For example, the heating or cooling capacity of air conditioning systems, as well as the energy content of fuels such as natural gas, is often expressed in BTUs.
For comparison, 1 BTU is roughly equivalent to the energy released by burning a match. In practical terms, it's a relatively small unit of energy, but it's useful for everyday applications involving heating or cooling.

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.
