Conversion Formula
The formula to convert watts to horsepower is simple: divide the number of watts by 745.7, because one horsepower equals 745.7 watts. For example, if you have 1500 watts, you divide 1500 by 745.7, resulting in approximately 2.01 horsepower. This works because the units are based on power equivalence.
Conversion Example
- Convert 50 watts into horsepower:
- Divide 50 by 745.7
- 50 / 745.7 ≈ 0.067 horsepower
- Convert 100 watts into horsepower:
- Divide 100 by 745.7
- 100 / 745.7 ≈ 0.134 horsepower
- Convert 200 watts into horsepower:
- Divide 200 by 745.7
- 200 / 745.7 ≈ 0.268 horsepower
- Convert 500 watts into horsepower:
- Divide 500 by 745.7
- 500 / 745.7 ≈ 0.669 horsepower
