mW to GW Conversion

How to convert one unit into another unit?

Step1: Identify the units you have. UnitA

Step2: Identify the Output units. UnitB

Step3: find the conversion factor:

If x UnitA = y UnitB

While converting from unitA to unitB
Conversionfactor=

While converting from unitB to unitA
Conversionfactor=

Conversion factor signifies that,
1 unitA =unitB
1 unitB = unitA

Step4: Multiply inputValue with conversion factor:

Converting from unitA to unitB
unitB
Converting from unitB to unitAunitA

Input Unit : mW

Output Unit: GW

find the conversion factor:

we know 1 mW=1e-12GW
And, 1 GW=1000000000000mW

While converting from mW to GW
Conversionfactor=1e-12/1 =1e-12

Multiply inputValue with the conversion factor:
Answer In GW=conversionFactor*inputValue GW
4321 mW =1e-12*4321=4.321e-9GW
