How to Convert Sun's Mass to Dalton
To convert solar masses to kg: multiply by 1.98847 × 10³⁰.
M☉ = 1.98847 × 10³⁰ kg ≈ 333,000 M⊕ ≈ 1,048 M_Jupiter.
For example, 1 Sun's Mass (M☉) = 1.197485e+57 Dalton (Da).

About Sun's Mass (M☉)
Definition
The solar mass is the mass of the Sun, approximately 1.989 × 10³⁰ kilograms — about 333,000 times the mass of Earth.
Mathematical Relationship
M☉ = 1.98847 × 10³⁰ kg ≈ 333,000 M⊕ ≈ 1,048 M_Jupiter.
Conversion Formula
To convert solar masses to kg: multiply by 1.98847 × 10³⁰.
Practical Applications
Expressing stellar masses: Betelgeuse ≈ 15 M☉, Sirius ≈ 2 M☉, a typical neutron star ≈ 1.4 M☉.
Interesting Facts
The Sun loses about 5 million tonnes per second through nuclear fusion (E=mc²), but that's only 10⁻¹³ M☉ per year.
Common Mistakes
The Sun is losing mass continuously through radiation and solar wind — its mass is not quite constant over billions of years.
Educational Tips
Almost everything in astronomy uses solar masses: stars (0.1–100 M☉), galaxies (10⁹–10¹² M☉), black holes (3–10⁹ M☉).
About Dalton (Da)
Definition
The dalton is a unit of mass equal to one unified atomic mass unit (1/12 of a carbon-12 atom), approximately 1.661 × 10⁻²⁷ kg.
Mathematical Relationship
1 Da = 1 u = 1.6605390666 × 10⁻²⁷ kg. Proteins range from ~5 kDa to >1,000 kDa.
Conversion Formula
To convert Da to kg: multiply by 1.6605390666 × 10⁻²⁷. 1 kDa = 1,000 Da.
Practical Applications
Protein molecular weights (hemoglobin ≈ 64.5 kDa), DNA fragment sizing, and antibody characterization.
Interesting Facts
Titin, the largest known protein, has a molecular weight of about 3,800 kDa (3.8 MDa). The average protein is ~40–50 kDa.
Common Mistakes
The dalton and u are identical — they're just preferred in different fields (Da in biology, u in chemistry/physics).
Educational Tips
If a paper says a protein is '50 kDa,' that's 50,000 atomic mass units — about 50,000 hydrogen atoms' worth of mass.
