What is the speed of light per hour in miles?

Answer 1

The speed of light is 186,000 miles per second,

and miles per minute (60 seconds x 186,000) would be 11,160,000 miles per minute

therefore

miles per hour (60 minutes x 60 seconds or 3600 seconds x 186,000) = 669,600,000 miles per hour

Answer 2

The speed of light in a vacuum is approximately 186,282 miles per second. To convert this to miles per hour, you would multiply this value by the number of seconds in an hour (3,600 seconds). Therefore, the speed of light per hour is approximately 670,616,800 miles per hour.

Answer 3

The letter c is used to denote the speed of light. It is around 671 million miles per hours.

Because speed of light is such a big number in mph or kph, we often use something called a natural unit. This makes life easy since the speed of light is 1 natural unit.

That answer is incorrect. The correct answer is 670,616,280 miles per hour.
