How the formula works
Both terawatt and milliwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in terawatts by 1.000000e+15 to get milliwatts. To reverse the conversion, multiply a milliwatt value by 1.000000e-15 to get back to terawatts.
Frequently asked questions
What is Terawatt (TW)?
A Terawatt (TW) equals 1e+12 watt(s), a scaled unit of electrical power used for tera-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 terawatts to milliwatts?
Multiply the terawatt value by 1.000000e+15 to get the equivalent in milliwatts. For example, 5 TW × 1.000000e+15 = 5.000000e+15 mW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+15 is an exact, non-rounded value.
Can I convert milliwatts back to terawatts?
Yes. Divide the milliwatt value by 1.000000e+15, or multiply it by 1.000000e-15, to get terawatts.
