Conversion Formula
The formula to convert kilowatts to horsepower is straightforward: multiply the number of kilowatts by 1.34102. This works because 1 kW equals 1.34102 hp, a fixed conversion factor based on their definitions. For example, if you have 10 kW, multiplying 10 by 1.34102 gives 13.4102 hp. This conversion is used because horsepower measures mechanical power, and kilowatts are a metric measure, so the factor aligns them for practical use.
Conversion Example
- Convert 25 kW to hp:
- Step 1: Write the formula: hp = kw * 1.34102
- Step 2: Insert 25 for kw: hp = 25 * 1.34102
- Step 3: Multiply: 25 * 1.34102 = 33.5255
- Result: 25 kW equals approximately 33.53 hp.
- Convert 60 kW to hp:
- Step 1: Formula: hp = 60 * 1.34102
- Step 2: Multiply: 60 * 1.34102 = 80.4612
- Result: 60 kW equals about 80.46 hp.
- Convert 100 kW to hp:
- Step 1: Use the formula: hp = 100 * 1.34102
- Step 2: Multiply: 100 * 1.34102 = 134.102
- Result: 100 kW equals roughly 134.10 hp.
