Convert 20 Microwatt (µW) to Megawatt (MW).

20 Microwatt equals 2.000000e-11 Megawatt. Multiply 20 by 1.000000e-12.

20 Microwatt = 2.000000e-11 Megawatt

Worked example: converting Microwatt to Megawatt

Step 1 — start with the formula. MW = µW × 1.000000e-12
Step 2 — substitute your figure. 20 µW × 1.000000e-12
Step 3 — read the result. 20 µW = 2.000000e-11 MW
Step 4 — check it in reverse. µW = MW × 1.000000e+12 returns 20 µW, which matches the figure you started with.
