Horsepower (metric) to Milliwatts conversion

How to convert horsepower (metric) to milliwatts?

Sure! Let's start by understanding the conversion from metric horsepower (hp) to milliwatts (mW).

Conversion Factor

1 metric horsepower (hp) is defined as 735.49875 watts (W).

To convert watts (W) to milliwatts (mW), you use the fact that: 1 watt (W) = 1,000 milliwatts (mW).

Calculation

So, if you want to convert 1 metric horsepower (hp) to milliwatts (mW), you first convert hp to watts and then convert watts to milliwatts:

1 hp (metric) = 735.49875 W

735.49875 W * 1,000 mW/W = 735,498.75 mW

Therefore: 1 hp (metric) = 735,498.75 mW

Real-world Examples for Other Quantities of Metric Horsepower

1. Small Engines (e.g., Lawn Mowers):

   • A typical lawnmower might use a 5 hp (metric) engine.
   • 5 hp = 5 * 735.49875 W = 3,677.49375 W
   • 3,677.49375 W * 1,000 = 3,677,493.75 mW

2. Automobiles:

   • A compact car might have an engine rating of about 100 hp (metric).
   • 100 hp = 100 * 735.49875 W = 73,549.875 W
   • 73,549.875 W * 1,000 = 73,549,875 mW

3. Sports Cars:

   • A sports car might have an engine rating of around 400 hp (metric).
   • 400 hp = 400 * 735.49875 W = 294,199.5 W
   • 294,199.5 W * 1,000 = 294,199,500 mW

4. Highly Powered Machines (e.g., Locomotives):

   • Some modern locomotives may have engines rated at 3,500 hp (metric).
   • 3,500 hp = 3,500 * 735.49875 W = 2,573,245.625 W
   • 2,573,245.625 W * 1,000 = 2,573,245,625 mW

Summary

1 metric horsepower (hp) is equivalent to 735,498.75 milliwatts (mW). This conversion and understanding allows us to translate various real-world power ratings into milliwatt terms for different applications ranging from small engines to substantial machinery.
