Convert Sun's mass to petagram
Please provide values below to convert Sun's mass [M_sun] to petagram [Pg], or Convert petagram to Sun's mass.
How to Convert Sun's Mass to Petagram
1 M_sun = 1.989e+18 Pg
Example: convert 15 M_sun to Pg:
15 M_sun = 15 × 1.989e+18 Pg = 2.9835e+19 Pg

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.
Petagram
A petagram (Pg) is a unit of mass equal to 10^15 grams or one quadrillion grams.
History/Origin
The petagram was introduced as part of the metric system's prefixes to represent extremely large masses, following the adoption of the International System of Units (SI). It is derived from the prefix 'peta-' which denotes 10^15.
Current Use
The petagram is primarily used in scientific contexts to quantify very large masses, such as in astronomy and geology, but is rarely used in everyday measurements.
