How the formula works
Both milliwatt and hectowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliwatts by 0.00001 to get hectowatts. To reverse the conversion, multiply a hectowatt value by 100000 to get back to milliwatts.
Frequently asked questions
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.
What is Hectowatt (hW)?
A Hectowatt (hW) equals 100 watt(s), a scaled unit of electrical power used for hecto-scale electrical work.
How do I convert milliwatts to hectowatts?
Multiply the milliwatt value by 0.00001 to get the equivalent in hectowatts. For example, 5 mW × 0.00001 = 0.00005 hW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.00001 is an exact, non-rounded value.
Can I convert hectowatts back to milliwatts?
Yes. Divide the hectowatt value by 0.00001, or multiply it by 100000, to get milliwatts.
