To convert solar radii to millimeters, multiply the value by 695,700,000,000. To go the other way, multiply millimeters by 1.4374 × 10⁻¹² to get solar radii.
| Solar Radii (R☉) | Millimeters (mm) |
|---|---|
| 1 R☉ | 695,700,000,000 mm |
| 2 R☉ | 1,391,400,000,000 mm |
| 5 R☉ | 3,478,500,000,000 mm |
| 10 R☉ | 6,957,000,000,000 mm |
| 20 R☉ | 13,914,000,000,000 mm |
| 50 R☉ | 34,785,000,000,000 mm |
| 100 R☉ | 69,570,000,000,000 mm |
| 500 R☉ | 347,850,000,000,000 mm |
| 1,000 R☉ | 695,700,000,000,000 mm |
25 R☉ × 695,700,000,000 = 17,392,500,000,000 mm
Try this example →250 R☉ × 695,700,000,000 = 173,925,000,000,000 mm
Try this example →Solar radius (R☉). The nominal solar radius is 695,700 km, used as a yardstick for the size of stars.
Millimeter (mm). A millimeter is one thousandth of a meter, used for small measurements such as thickness and rainfall.
There are 695,700,000,000 millimeters in one solar radius.
Multiply the number of solar radii by 695,700,000,000. For example, 10 solar radii equal 6,957,000,000,000 millimeters.
One millimeter equals 1.4374 × 10⁻¹² solar radii.
