How the formula works

Both megawatt and nanowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megawatts by 1.000000e+15 to get nanowatts. To reverse the conversion, multiply a nanowatt value by 1.000000e-15 to get back to megawatts.

Frequently asked questions

What is Megawatt (MW)?

A Megawatt (MW) equals 1e+6 watt(s), a scaled unit of electrical power used for mega-scale electrical work.

What is Nanowatt (nW)?

A Nanowatt (nW) equals 1e-09 watt(s), a scaled unit of electrical power used for nano-scale electrical work.

How do I convert megawatts to nanowatts?

Multiply the megawatt value by 1.000000e+15 to get the equivalent in nanowatts. For example, 5 MW × 1.000000e+15 = 5.000000e+15 nW.

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 nanowatts back to megawatts?

Yes. Divide the nanowatt value by 1.000000e+15, or multiply it by 1.000000e-15, to get megawatts.
