Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
Picowatt and Erg measure different quantities, so no single result applies.

Formula
Picowatt (pW) measures power, while Erg (erg) measures energy. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
pW relates to its own power base unit by a factor of 0. erg relates to its own energy base unit by a factor of 1e-07.
Conversion table
| Picowatt (pW) | 0 × power base unit |
| Erg (erg) | 1e-07 × energy base unit |

Frequently asked questions
Can Picowatt be converted to Erg?
Not directly. Picowatt measures power and Erg measures energy. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Picowatt used for?
The Picowatt (pW) is a unit of power. Picowatt is 1e-12 watt units.
What is Erg used for?
The Erg (erg) is a unit of energy. An erg is a CGS energy unit.
Why does the converter show an incompatible units message?
The Universal Converter only calculates a numeric result when both units share the same physical dimension. Since Picowatt and Erg don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Picowatt to instead?
Use another power unit, such as one of the related Picowatt conversions linked below.
What should I convert Erg to instead?
Use another energy unit, such as one of the related Erg conversions linked below.

About this conversion
This page compares Picowatt (pW) and Erg (erg) within the engineering converter.
Picowatt is 1e-12 watt units. An erg is a CGS energy unit.
Because Picowatt measures power and Erg measures energy, the two units are not directly convertible: there is no fixed ratio that turns one into the other without additional information.
The calculator above will report that these units are not compatible. For a working result, choose two units from the same measurement family — see the related conversions below.
