How the formula works
Both watt and microwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in watts by 1.000000e+06 to get microwatts. To reverse the conversion, multiply a microwatt value by 0.000001 to get back to watts.
Frequently asked questions
What is Watt (W)?
The watt (W) is the SI unit of power, equal to one joule of energy transferred per second.
What is Microwatt (uW)?
A Microwatt (uW) equals 1e-06 watt(s), a scaled unit of electrical power used for micro-scale electrical work.
How do I convert watts to microwatts?
Multiply the watt value by 1.000000e+06 to get the equivalent in microwatts. For example, 5 W × 1.000000e+06 = 5.000000e+06 uW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+06 is an exact, non-rounded value.
Can I convert microwatts back to watts?
Yes. Divide the microwatt value by 1.000000e+06, or multiply it by 0.000001, to get watts.
