What are BTUs and Watts?
British thermal unit per hour
Definition: The British thermal unit per hour (symbol: BTU/h) is a unit of power commonly used in the United States. It is often abbreviated as “BTU”, which is the same abbreviation as the British Thermal Unit (a unit of heat measurement).
One watt (a power unit derived from the International System of Units) equals approximately 3.41214 BTU/h.
History/Origin: The British Thermal Unit per hour is based on the British Thermal Unit (Symbol: Btu or BTU), which is the traditional American unit of heat, which is a type of energy transfer, where energy is transferred from a hotter substance to a cooler substance.
A BTU is specifically defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It has many different definitions, but all are equivalent to about 1,055 joules.
Current Use: When you fire up your gas grill, for example, it may put out 40,000 BTUs, effectively heating your grill to a searing temperature suitable for summer barbecues. BTU/hour is not a widely used unit.
Multiples of watt-hours (usually kilowatt-hours) are more commonly used than BTUs/hour, even in the United States.
Watt
Definition: The watt (symbol: W) is a derived unit of power from the SI (International System of Units). It is defined as 1 joule per second and is used to quantify the rate of energy transfer.
History/Origin: Named after the Scottish inventor James Watt, the concept was first introduced in 1882 by William Siemens, who defined it as “the power transmitted by an ampere of electric current through a potential difference in volts”. This was the definition used in the existing system of units at the time.
In 1908, the “International” definition was introduced and Siemens’ definition was adopted as the International Watt. These definitions remained in use until 1948, when the International Conference on Weights and Measures redefined the watt as an absolute unit, using only mass, time, and length.
1 Absolute Watt equals 1.00019 International Watts. 1960 saw the adoption of the Absolute Watt as the SI unit of power.
Current Use: As a derivative of the International System of Units for power, the watt, and all its multiples and fractional multiples, are used worldwide in many fields, from radio transmission to the power industry.
The watt as a unit of power should not be confused with its energy counterpart, the watt-hour (and all its multiples/fractional multiples).
For example, a standard LED light bulb may use about 10 watts of power, much less than a traditional 60-watt incandescent bulb, demonstrating a leap in energy efficiency.
Understanding these units can help make informed energy use decisions in everyday life, from choosing the right appliances to managing your home energy budget smartly.

Conversion of BTU to watts/watt to BTU conversion: conversion formulas and practical applications
Understanding the conversion of BTU and watts/watt to BTU/hr, in addition to the conversion table above, provides an understanding of the core conversion formulas and calculations that link these two key energy measurement units.
Converting BTUs to Watts
To convert BTU to watts, you can use a simple formula: watts = BTU x 0.293
For example, if your air conditioner is rated at 12,000 BTUs, multiply 12,000 by 0.293 to get the watts equivalent: 12,000 BTUs x 0.293 = 3,516 watts
Multiplying watts to BTU/hr
It’s also important to do it the other way around. To convert watts to BTUs, use the following formula: BTU = watts x 3.41
So, if an appliance draws 600 watts, its BTU power is calculated as follows: 600 watts x 3.41 = 2,046 BTUs
Converting kilowatts to watts
Sometimes you need to convert kilowatts (kW) to watts (W). This is easy because 1 kilowatt equals 1,000 watts: Watt = kW x 1,000
For example, 3 kilowatts is: 3 kilowatts x 1,000 = 3,000 watts. There is also How To Convert Watts To Amps that you can learn.
Practical Example
Suppose you have a heater rated at 5,000 watts. To find its equivalent in BTUs and kWs, you can use the above formula:
1. Convert watts to BTUs: 5,000 watts x 3.41 = 17,050 BTUs
2. Converting Watts to Kilowatts: 5,000 Watts ÷ 1,000 = 5 Kilowatts
By understanding and applying these conversions, you can better manage and compare the energy consumption of different systems and appliances. This knowledge is essential for optimizing energy use and improving energy efficiency in both domestic and commercial environments.
