Horsepower Formula:
From: | To: |
Definition: This calculator converts power measurements from kilowatts (kW) to horsepower (HP).
Purpose: It helps engineers, mechanics, and technicians convert between these common power units used in automotive, industrial, and electrical applications.
The calculator uses the formula:
Where:
Explanation: 1 kilowatt is approximately equal to 1.341 horsepower. This conversion factor is derived from the exact definition of 1 HP = 745.7 watts.
Details: Accurate conversion between kW and HP is essential when working with equipment specifications, engine ratings, or electrical systems that use different measurement standards.
Tips: Simply enter the power value in kilowatts (must be > 0) and the calculator will provide the equivalent horsepower.
Q1: What's the exact conversion factor?
A: The exact conversion is 1 kW = 1.34102209 HP, but 1.341 is typically precise enough for most applications.
Q2: Is this mechanical or electrical horsepower?
A: This calculator uses mechanical horsepower (also called imperial horsepower), which is the most common standard.
Q3: How do I convert back from HP to kW?
A: Divide the horsepower value by 1.341 (or multiply by 0.7457).
Q4: Why do some countries use kW while others use HP?
A: kW is part of the metric system (SI units) while HP is part of the imperial system. Most countries have officially adopted kW but HP remains common in automotive applications.
Q5: Are there different types of horsepower?
A: Yes, there are mechanical (imperial), metric, boiler, and electrical horsepower, each with slightly different values.
