About Converting Solar mass to Earth mass
Solar mass and Earth mass both describe astronomical distances at very different scales — one for measuring within our solar system, the other for the distances between stars — and converting between them helps put the scale of space into perspective. Specifically: Solar mass is used in astronomy, and earth mass.
Formula
earth mass = solar mass × 332954.355179
This factor comes from each unit's defined relationship to the category's base unit: 1 solar mass equals 1.98847e+30 base units, and 1 earth mass equals 5.9722e+24 base units, so dividing one by the other gives the direct solar mass-to-earth mass factor of 332954.355179.
Simple example
1 Msun × 332954.3552 = 332,954.3552 Mearth
1 solar mass = 332,954.3552 earth mass.
Real-world example
4.24 Msun × 332954.3552 = 1,411,726.466 Mearth
4.24 solar mass = 1,411,726.466 earth mass.
