Watt to Megawatt Converter

Power · unit-converter

Convert Watt 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 Watt

The watt is the SI unit of power (one joule per second). All linear units in this converter are defined by a fixed watt equivalent.

About Megawatt

One megawatt is one million watts. Utility generation, large drives, and grid studies use MW.

How to convert watts to megawatts

1 watt is equal to 0.000001 megawatt when both are expressed in watt-equivalents:

1 w = (1 W ÷ 1,000,000 W) megaw = 0.000001 megaw

Each watt is defined as 1 W and each megawatt as 1,000,000 W in this tool, so one w equals 1 ÷ 1,000,000 megaw = 0.000001 megaw.

Let d(w) be the numeric value in Watt (w), and d(megaw) the value in Megawatt (megaw). Then:

d(megaw) = d(w) × (1 / 1,000,000)

Equivalently, divide by how many w fit into one megaw (watts per megaw divided by watts per w):

d(megaw) = d(w) ÷ 1000000

Or: megawatt = watt ÷ 1000000

Examples

Example #1: Convert 1 w to megawatt

1 w = 1 w × (1/1,000,000) megaw = 0.000001 megaw

1 w = 1 w ÷ 1000000 = 0.000001 megaw

Intermediate watts: 1 W

Example #2: Convert 10 w to megawatt

10 w = 10 w × (1/1,000,000) megaw = 0.00001 megaw

10 w = 10 w ÷ 1000000 = 0.00001 megaw

Intermediate watts: 10 W

Summary

To convert Watt to Megawatt, multiply the value in w by the ratio of watts per w divided by watts per megaw. Equivalently: value_megaw = value_w × (1 / 1000000). Numerically, 1 w equals 0.000001 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 Watt to Megawatt is 1.000000e-6 (1 w = 0.000001 megaw).
