Unit definition
Metric horsepower (PS) One metric horsepower equals 735.49875 watt.
Unit history
Metric horsepower is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert PS to watt.
3. Convert the base value to MW and apply your display precision.
Understand the result before using it
Metric horsepower to Megawatts converts a value measured in Metric horsepower (PS) into the equivalent value in Megawatts (MW). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 735.49875 ÷ 1000000
Assumptions
- Metric horsepower and Megawatts represent the same power quantity.
- The input is expressed in PS; the output is expressed in MW.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 PS = 0.00073549875 MW. For another value, apply the same relationship and round only to the precision your source measurement supports.
When to use it
Good uses
- Read a PS measurement in a document that expects MW.
- Compare a metric horsepower value with a value reported in megawatts.
- Check the PS-to-MW arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Do not confuse PS with another unit that has a similar name or symbol.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.
