⚡ Earth Radii to Miles: the quick answer

1 R⊕ = 3,958.76 mi 1 Earth radius equals 3,958.76 miles

To convert Earth radii to miles, multiply the value by 3,958.76. To go the other way, multiply miles by 0.000252604 to get Earth radii.

↔ Convert miles to Earth radii instead

🧮 Formula

Earth Radii to Miles
mi = R⊕ × 3,958.76
Miles to Earth Radii
R⊕ = mi × 0.000252604

Where

  • R⊕ = the length in Earth radii
  • mi = the length in miles
Every unit here is defined by its length in meters, so the conversion factor is (meters per Earth radius) ÷ (meters per mile).
