Please provide values below to convert Sun's mass [M_sun] to kilogram [kg], or Convert kilogram to Sun's mass.
How to Convert Sun's Mass to Kilogram
1 M_sun = 1.989e+30 kg
Example: convert 15 M_sun to kg:
15 M_sun = 15 × 1.989e+30 kg = 2.9835e+31 kg

Sun's Mass
The Sun's mass (M_sun) is a standard unit of mass used in astronomy to express the mass of other stars and celestial objects, approximately equal to 1.989 × 10^30 kilograms.
History/Origin
The concept of using the Sun's mass as a unit originated in the early 20th century as astronomers sought a convenient standard for stellar masses. It became widely adopted in astrophysics for its practicality and ease of comparison.
Current Use
Today, M_sun is commonly used in astrophysics and astronomy to describe the mass of stars, planets, and other celestial bodies, facilitating standardized communication and calculations within the scientific community.
Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI), defined as the mass of the International Prototype Kilogram, a platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures.
History/Origin
The kilogram was originally defined in 1795 as the mass of one liter of water. It was later represented by a platinum standard in 1875, known as the International Prototype Kilogram, which served as the global standard until 2019.
Current Use
Today, the kilogram is defined by the Planck constant, fixed at exactly 6.62607015×10⁻³⁴ joule seconds, ensuring greater precision and stability in measurements worldwide. It is widely used in science, industry, and commerce for measuring mass.
