Numerical value
As opposed to the light year, whose value more or less depends on the definition of year, the value of the light minute is defined exactly.
- velocity of light in vacuum: 299,792,458 m/s [1] (meters/second)
- 1 min = 60 s
- 1 light minute = 17,987,547,480 m = 1.7987547 * 1010m
Comparison to other Units
- 1 AU = 8.31 light minutes
- 1 light minute = 17,987,547.480 km
- 1 light minute = 11,176,943.823 mi[2]
- 1 light minute = 59,014,263,385.826 ft[3] = 5.9014263 * 10<sump>10</sup> ft
- 1 light minute = 19,671,421,128.608 yd[4] = 1.9671421 * 1010 yd
