To convert light hours to nautical miles, multiply the value by 582,750,000. To go the other way, multiply nautical miles by 1.716 × 10⁻⁹ to get light hours.
| Light Hours (lh) | Nautical Miles (NM) |
|---|---|
| 1 lh | 582,750,000 NM |
| 2 lh | 1,165,500,000 NM |
| 5 lh | 2,913,750,000 NM |
| 10 lh | 5,827,500,000 NM |
| 20 lh | 11,655,000,000 NM |
| 50 lh | 29,137,500,000 NM |
| 100 lh | 58,275,000,000 NM |
| 500 lh | 291,375,000,000 NM |
| 1,000 lh | 582,750,000,000 NM |
250 lh × 582,750,000 = 145,687,000,000 NM
Try this example →Light hour (lh). A light hour is the distance light travels in an hour, about 1.08 billion kilometers.
Nautical mile (NM). A nautical mile is exactly 1,852 meters, based on one minute of latitude, and is used in shipping and aviation.
There are 582,750,000 nautical miles in one light hour.
Multiply the number of light hours by 582,750,000. For example, 10 light hours equal 5,827,500,000 nautical miles.
One nautical mile equals 1.716 × 10⁻⁹ light hours.
