1 ct = 1.0058 × 10⁻³⁴ M☉ 1 carat equals 1.0058 × 10⁻³⁴ solar masses

To convert carats to solar masses, multiply the value by 1.0058 × 10⁻³⁴. To go the other way, multiply solar masses by 9.94235 × 10³³ to get carats.

↔ Convert solar masses to carats instead

🧮 Formula

Carats to Solar Masses
M☉ = ct × 1.0058 × 10⁻³⁴
Solar Masses to Carats
ct = M☉ × 9.94235 × 10³³

Where

  • ct = the weight in carats
  • M☉ = the weight in solar masses
Every unit here is defined by its weight in kilograms, so the conversion factor is (kilograms per carat) ÷ (kilograms per solar mass).
