Milliwatt to Megawatt Converter
Power · unit-converter
Convert Milliwatt to Megawatt 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 Milliwatt
One milliwatt is one thousandth of a watt. Common in RF, fiber optics, and low-power electronics.
About Megawatt
One megawatt is one million watts. Utility generation, large drives, and grid studies use MW.
How to convert milliwatts to megawatts
1 milliwatt is equal to 1.00000000e-9 megawatt when both are expressed in watt-equivalents:
1 mw = (0.001 W ÷ 1,000,000 W) megaw = 1.00000000e-9 megaw
Each milliwatt is defined as 0.001 W and each megawatt as 1,000,000 W in this tool, so one mw equals 0.001 ÷ 1,000,000 megaw = 1.00000000e-9 megaw.
Let d(mw) be the numeric value in Milliwatt (mw), and d(megaw) the value in Megawatt (megaw). Then:
d(megaw) = d(mw) × (0.001 / 1,000,000)
Equivalently, divide by how many mw fit into one megaw (watts per megaw divided by watts per mw):
d(megaw) = d(mw) ÷ 1.00000000e+9
Or: megawatt = milliwatt ÷ 1.00000000e+9
Examples
Example #1: Convert 1 mw to megawatt
1 mw = 1 mw × (0.001/1,000,000) megaw = 0.000000001 megaw
1 mw = 1 mw ÷ 1.00000000e+9 = 0.000000001 megaw
Intermediate watts: 0.001 W
Example #2: Convert 10 mw to megawatt
10 mw = 10 mw × (0.001/1,000,000) megaw = 0.00000001 megaw
10 mw = 10 mw ÷ 1.00000000e+9 = 0.00000001 megaw
Intermediate watts: 0.01 W
Summary
To convert Milliwatt to Megawatt, multiply the value in mw by the ratio of watts per mw divided by watts per megaw. Equivalently: value_megaw = value_mw × (0.001 / 1000000). Numerically, 1 mw equals 1e-9 megaw.
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 Milliwatt to Megawatt is 1.000000e-9 (1 mw = 1e-9 megaw).
