About Converting Megawatts to Picowatts
Megawatt and Picowatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Megawatt is 1000000 watt units, and picowatt is 1e-12 watt units.
Formula
picowatts = megawatts × 1e+18
This factor comes from each unit's defined relationship to the category's base unit: 1 megawatt equals 1000000 base units, and 1 picowatt equals 1e-12 base units, so dividing one by the other gives the direct megawatt-to-picowatt factor of 1e+18.
Simple example
1 MW × 1e+18 = 1e+18 pW
1 megawatt = 1e+18 picowatts.
Real-world example
100 MW × 1e+18 = 1e+20 pW
100 megawatts = 1e+20 picowatts.
Conversion table
| Megawatt (MW) | Picowatt (pW) |

Reverse conversion: Picowatt to Megawatt
1e+18 pW × 1e-18 = 1 MW
1e+18 picowatts = 1 megawatt.
megawatts = picowatts × 1e-18
