How the formula works
Both milliwatt and megawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliwatts by 1.000000e-09 to get megawatts. To reverse the conversion, multiply a megawatt value by 1.000000e+09 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 Megawatt (MW)?
A Megawatt (MW) equals 1e+6 watt(s), a scaled unit of electrical power used for mega-scale electrical work.
How do I convert milliwatts to megawatts?
Multiply the milliwatt value by 1.000000e-09 to get the equivalent in megawatts. For example, 5 mW × 1.000000e-09 = 5.000000e-09 MW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-09 is an exact, non-rounded value.
Can I convert megawatts back to milliwatts?
Yes. Divide the megawatt value by 1.000000e-09, or multiply it by 1.000000e+09, to get milliwatts.
