A W to BTU calculator is an essential tool that helps convert the power output (in watts) of electrical appliances to their heat output (in BTUs). This conversion is particularly important in fields such as HVAC (heating, ventilation, and air conditioning) where the heating or cooling capacity needs to be accurately understood and communicated in universally recognized units.
Formula of W to BTU Calculator
To convert watts to BTUs, we use the formula:
For instance, if an appliance has a power consumption of 100 watts, the equivalent heat output would be calculated as:
BTU = 100 × 3.412142 = 341.2142 BTUs
This formula provides a straightforward method for translating the electrical energy used by a device into its heating or cooling potential.
Conversion Table
To simplify the process further, here is a handy table for common wattages and their corresponding BTU outputs:
| Watts (W) | BTUs |
|---|---|
| 100 | 341 |
| 500 | 1706 |
| 1000 | 3412 |
| 2000 | 6824 |
This table allows you to quickly reference and convert typical wattages without needing to perform the calculation each time.
Example of W to BTU Calculator
Example 1: If you have an air conditioner that operates at 1500 watts, using our formula:
BTU = 1500 × 3.412142 = 5118.213 BTUs
Example 2: For a quick reference using the table, a 500-watt device corresponds to 1706 BTUs.
