How to convert watts to BTU/hr (W to BTU/hr)

The formula for converting watts to BTU/hr is: BTU/hr = W × 3.412141635133. To calculate the watt value in BTU/hr first substitute the watt value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 watt in BTU/hr we follow these steps:

BTU/hr = W × 3.412141635133

BTU/hr = 1 × 3.412141635133

BTU/hr = 3.412141635133

In other words, 1 watt is equal to 3.412141635133 BTU/hr.


Example Conversion

Let's take a look at an example. The step-by-step process to convert 2 watts to BTU/hr is:

  1. Understand the conversion formula: BTU/hr = W × 3.412141635133
  2. Substitute the required value. In this case we substitute 2 for W so the formula becomes: BTU/hr = 2 × 3.412141635133
  3. Calculate the result using the provided values. In our example the result is: 2 × 3.412141635133 = 6.824283270266 BTU/hr

In summary, 2 watts is equal to 6.824283270266 BTU/hr.


Converting BTU/hr to watts

In order to convert the other way around i.e. BTU/hr to watts, you would use the following formula: W = BTU/hr × 0.29307107. To convert BTU/hr to watts first substitute the BTU/hr value into the above formula, and then execute the calculation. If we wanted to calculate 1 BTU/hr in watts we follow these steps:

W = BTU/hr × 0.29307107

W = 1 × 0.29307107

W = 0.29307107

Or in other words, 1 BTU/hr is equal to 0.29307107 watts.


Conversion Unit Definitions

What is a Watt?

A watt (W) is a unit of power that measures the rate at which energy is transferred, used, or produced. It represents the amount of energy consumed or generated per unit of time. Here's an example to help illustrate the concept of a watt:
Consider a light bulb with a power rating of 60 watts. This means that the light bulb consumes or emits energy at a rate of 60 joules per second. In simpler terms, it indicates that the light bulb uses 60 watts of power to produce light.
If you were to leave this light bulb turned on for one hour, it would consume a total of 60 watts multiplied by 3600 seconds (the number of seconds in an hour), which equals 216,000 joules or 216 kilojoules of energy. This demonstrates how power consumption, measured in watts, can be related to the total energy usage over a specific time period.
The watt is a fundamental unit of power in the International System of Units (SI) and is widely used in various applications. It provides a common basis for measuring and comparing the power ratings of electrical appliances, devices, machinery, and systems.
In practical terms, wattage is commonly seen on electrical appliances, such as laptops, refrigerators, air conditioners, and electric motors. It helps consumers understand the power requirements or capabilities of these devices and allows for efficient energy management and comparison between different options.
In summary, a watt is a unit of power that represents the rate at which energy is transferred or used. It is denoted by the symbol W. The example of a 60-watt light bulb demonstrates how wattage can be used to quantify power consumption or generation in various electrical devices or systems.

What is a BTU/hr?

BTU/hr stands for British Thermal Units per hour and is a unit of power used to measure the rate of heat transfer or energy conversion. It represents the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit in one hour.
To provide an example, let's consider a residential air conditioning unit with a cooling capacity of 12,000 BTU/hr. This means that the air conditioner has the capability to remove or transfer 12,000 British Thermal Units of heat from the air per hour.
In practical terms, this cooling capacity indicates the ability of the air conditioner to cool a certain space. A higher BTU/hr rating implies that the air conditioner can cool a larger area or deal with a higher heat load.
For instance, a 12,000 BTU/hr air conditioner is typically suitable for cooling a small to medium-sized room or office space. However, the specific cooling requirements can vary depending on factors such as insulation, outdoor temperature, and desired indoor temperature.
BTU/hr is commonly used in heating, ventilation, and air conditioning (HVAC) systems to specify the cooling or heating capacity of air conditioners, heaters, and other equipment. It helps determine the appropriate system size for different applications and ensure optimal temperature control.
In summary, BTU/hr (British Thermal Units per hour) is a unit of power used to measure the rate of heat transfer or energy conversion. The example of a 12,000 BTU/hr air conditioner demonstrates how this unit is used to specify the cooling capacity of HVAC systems and determine their suitability for different spaces.
