🧮 Formula

Stone to Earth Masses
M⊕ = st × 1.06331 × 10⁻²⁴
Earth Masses to Stone
st = M⊕ × 9.40461 × 10²³

Where

  • st = the weight in stone
  • M⊕ = the weight in Earth masses
Every unit here is defined by its weight in kilograms, so the conversion factor is (kilograms per stone) ÷ (kilograms per Earth mass).
