Megawatt to Milliwatt Converter
Power · unit-converter
Convert Megawatt to Milliwatt with a fixed input and output unit, step-by-step formula line, and reference tables. Linear units use SI watt definitions; mechanical hp uses 550 ft·lbf/s; BTU/h uses the IT BTU; dBm/dBW are logarithmic relative to 1 mW and 1 W. The full Power Converter also includes PS/CV, TR, kVA/MVA, and ft·lb/s.

About Megawatt
One megawatt is one million watts. Utility generation, large drives, and grid studies use MW.
About Milliwatt
One milliwatt is one thousandth of a watt. Common in RF, fiber optics, and low-power electronics.
How to convert megawatts to milliwatts
1 megawatt is equal to 1.00000000e+9 milliwatt when both are expressed in watt-equivalents:
1 megaw = (1,000,000 W ÷ 0.001 W) mw = 1.00000000e+9 mw
Each megawatt is defined as 1,000,000 W and each milliwatt as 0.001 W in this tool, so one megaw equals 1,000,000 ÷ 0.001 mw = 1.00000000e+9 mw.
Let d(megaw) be the numeric value in Megawatt (megaw), and d(mw) the value in Milliwatt (mw). Then:
d(mw) = d(megaw) × (1,000,000 / 0.001)
Equivalently, divide by how many megaw fit into one mw (watts per mw divided by watts per megaw):
d(mw) = d(megaw) ÷ 1.00000000e-9
Or: milliwatt = megawatt ÷ 1.00000000e-9
Examples
Example #1: Convert 1 megaw to milliwatt
1 megaw = 1 megaw × (1,000,000/0.001) mw = 1000000000 mw
1 megaw = 1 megaw ÷ 1.00000000e-9 = 1000000000 mw
Intermediate watts: 1,000,000 W
Example #2: Convert 10 megaw to milliwatt
10 megaw = 10 megaw × (1,000,000/0.001) mw = 10000000000 mw
10 megaw = 10 megaw ÷ 1.00000000e-9 = 10000000000 mw
Intermediate watts: 10,000,000 W
Summary
To convert Megawatt to Milliwatt, multiply the value in megaw by the ratio of watts per megaw divided by watts per mw. Equivalently: value_mw = value_megaw × (1000000 / 0.001). Numerically, 1 megaw equals 1000000000 mw.
Relationship context
Both units are SI / decimal power (watts and prefixes). Conversions use fixed watt factors, so results stay consistent with the definitions in this converter. The factor from Megawatt to Milliwatt is 1.000000e+9 (1 megaw = 1000000000 mw).
