The speed of light (

`c`

) approximates one foot per nanosecond.google: speed of light ...or... c the speed of light = 299 792 458 m / s first hyperlink: http://en.wikipedia.org/wiki/Speed_of_light google: speed of light to ft per second ...or ... c to ft per sec the speed of light = 983 571 056 feet per second first hyperlink: http://galileoandeinstein.physics.virginia.edu/lectures/spedlite.html google: 983571056 x 10^-9 983 571 056 x (10^(-9)) = 0.983571056 first hyperlink: none; mathematical expression usedThe

nano-prefix implies one-billionth of something; therefore, one nanosecond is one-billionth of a second.983,571,056 ft 1 second 983,571,056 ft -------------- x ------------- = ---------------- = 0.983571056 ft 1 second 1,000,000,000 1,000,000,000 The 'second' unit in the denominator of the left-hand fraction and the 'second' unit in the numerator of the right-hand fraction cancel each other leaving the answer in terms of feet (or faction of a foot).

`0.983571056 foot`

is approximately`1.643%`

shorter than`one foot`

. With respect to inches, light travels at a speed of about`11.802852672 inches per nanosecond`

`two-tenths of an inch`

short of a foot.
