Units explained
Sun's Mass
The solar mass (M(S)) is about 2.0E30 kg.
The standard unit for expressing stellar and galactic masses.
Astrophysics and cosmology.
Established as astronomers measured the Sun's gravitational influence.
Kilogram
The kilogram (kg) is the SI base unit of mass, defined by fixing the Planck constant h at 6.62607015E-34 J s.
From Greek 'khilioi' (thousand) plus 'gramma' (small weight).
The worldwide base unit of mass in science, commerce, and everyday life.
Adopted in 1795; redefined through the Planck constant on 20 May 2019.
Sun's Mass to Kilogram conversion formula
Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.
The relationship between sun's mass and kilograms:
To convert sun's mass to kilograms, multiply the value in sun's mass by 2e+30. To reverse, multiply kilograms by 5e-31.
How to use this converter

Step-by-step: convert sun's mass to kilograms
- Write down the value in sun's mass (M☉).
- Multiply that value by the factor 2e+30.
- The product is the equivalent value in kilograms (kg).
- To reverse, multiply the kilogram value by 5e-31.
Worked examples
Example 1 — Convert 1 M☉ to kg:
1 × 2e+30 = 2e+30 kg
Example 2 — Convert 100 M☉ to kg:
100 × 2e+30 = 2e+32 kg
