Convert BTU To kWh: Simple BTU To Killowatt-Hour Conversion + Chart

In many cases, you will need to convert BTU to kWh. For example, if you need to know how many kWh does your 12,000 BTU air conditioner uses every hour, you just need to convert BTU to kWh.

Let’s first summarize what BTU and kWh are:

  • BTU stands for British Thermal Unit. This is a unit of heat (cooling) and is defined as the amount of heat required to heat up (or cool) 1 pound of water by one degree (°F).
  • kWh stands for kilowatt-hour. This is a unit of electrical energy and is defined as an amount of electricity used to run a 1,000W (1kW) device for 1 hour.

How to convert BTU to kWh?

Simple. You just need to follow this conversion rule:

1 BTU is equal to 0.00029308323 kWh. That means that 3,412 BTU is equal to 1 kWh.

To calculate kWh from BTU you just need to multiply the BTUs by 0.00029308323. This is quite a small number and you will have to type a lot of you were to use a hand calculator to convert BTU to kWh.

To help you out, we have designed a dead simple BTU to kWh calculator that automatically (and dynamically) makes this conversion. Below the calculator, you will also find a BTU to kWh conversion chart with converted values (from 1 BTU to 100,000 BTU). On top of that, we showcase 4 examples (for 9,000 BTU, 12,000 BTU, 18,000 BTU, and 24,000 BTU) that will help you understand how to convert BTU to kWh.

Here is the calculator, followed by the chart and solved examples:

Let’s solve some examples to see how this BTU to kWh conversion works:

Example 1: How Many kWh Is 9,000 BTU?

To convert 9,000 BTU to kWh, we just multiply 9,000 BTU by 0.00029308323 kWh/BTU like this:

9,000 BTU × 0.00029308323 kWh/BTU = 2.64 kWh

Here you have it:

9,000 BTU is equal to 2.64 kWh.

Example 2: How Many kWh Is 12,000 BTU?

To convert 12,000 BTU to kWh, we just multiply 12,000 BTU by 0.00029308323 kWh/BTU like this:

12,000 BTU × 0.00029308323 kWh/BTU = 3.52 kWh

Here you have it:

12,000 BTU is equal to 3.52 kWh.

Example 3: How Many kWh Is 18,000 BTU?

To convert 18,000 BTU to kWh, we just multiply 18,000 BTU by 0.00029308323 kWh/BTU like this:

18,000 BTU × 0.00029308323 kWh/BTU = 5.28 kWh

Here you have it:

18,000 BTU is equal to 5.28 kWh.

Example 4: How Many kWh Is 24,000 BTU?

To convert 24,000 BTU to kWh, we just multiply 24,000 BTU by 0.00029308323 kWh/BTU like this:

24,000 BTU × 0.00029308323 kWh/BTU = 7.03 kWh

Here you have it:

24,000 BTU is equal to 7.03 kWh.
