Solar radii to Millimicrons Converter

1 solar radius (R☉) equals 6.957 × 1017 millimicrons (mµ).

Quick answer

  • 1 solar radius = 6.957 × 1017 millimicrons
  • 1 millimicron = 1.4374012 × 10-18 solar radii
  • Formula: mµ = R☉ × 6.957 × 1017

1 solar radius = 6.957 × 1017 millimicrons

How to convert solar radii to millimicrons

mµ = R☉ × 6.957 × 1017

To convert solar radii to millimicrons, multiply the number of solar radii by 6.957 × 1017.

Example: 1 R☉ to mµ

  1. Start with the value in solar radii: 1 R☉.
  2. Multiply by 6.957 × 1017: 1 × 6.957 × 1017 = 6.957 × 1017.
  3. Result: 1 solar radius = 6.957 × 1017 millimicrons.

Going the other way, 1 millimicron = 1.4374012 × 10-18 solar radii, so to convert millimicrons back to solar radii you divide by the same number. See millimicrons to solar radii.
