How the formula works
Both hectowatt and milliwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in hectowatts by 100000 to get milliwatts. To reverse the conversion, multiply a milliwatt value by 0.00001 to get back to hectowatts.
Frequently asked questions
What is Hectowatt (hW)?
A Hectowatt (hW) equals 100 watt(s), a scaled unit of electrical power used for hecto-scale electrical work.
What is Milliwatt (mW)?
A Milliwatt (mW) equals 1/1,000 watt(s), a scaled unit of electrical power used for milli-scale electrical work.
How do I convert hectowatts to milliwatts?
Multiply the hectowatt value by 100000 to get the equivalent in milliwatts. For example, 5 hW × 100000 = 500000 mW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 100000 is an exact, non-rounded value.
Can I convert milliwatts back to hectowatts?
Yes. Divide the milliwatt value by 100000, or multiply it by 0.00001, to get hectowatts.
