Conversion Formula
The formula used to convert watts to horsepower is: horsepower = watts / 745.7. This works because one horsepower equals exactly 745.7 watts, which is a standard unit measure. For example, if you have 1500 watts, dividing 1500 by 745.7 results in approximately 2.01 horsepower.
Conversion Example
- Suppose you want to convert 600 watts to horsepower.
- Step 1: Write down the formula: horsepower = watts / 745.7.
- Step 2: Plug in 600 watts: 600 / 745.7.
- Step 3: Calculate: 600 ÷ 745.7 ≈ 0.8043.
- Therefore, 600 watts equals about 0.8043 horsepower.
