How far does light travel in 1 millisecond, that is, in one thousandth of a second?

The speed of light is approximately 299,792 kilometers (186,282 miles) per second. Given a millisecond is a thousandth of a second, light will travel approximately 299.792 kilometers in one millisecond. ;

First of all, we have to convert the time into seconds: t = 1 m s = 0.001 s Light travels at speed of v = 3 ⋅ 1 0 8 m / s . The distance covered by the light during this time can be found with the formula v = t S ​ where S is the distance covered and t the time. By re-arranging this formula and by plugging the numbers into it, we find how far the light went in 1 millisecond: S = v t = ( 3 ⋅ 1 0 8 ) ( 0.001 s ) = 3 ⋅ 1 0 5 m .

Light travels approximately 300,000 meters, or 300 kilometers, in 1 millisecond. This is calculated by multiplying the speed of light (about 300 million meters per second) by the time converted into seconds (0.001 seconds). Thus, the distance covered in this very brief moment is significant even at such a high speed.
