Did you know this fun little fact

That it takes light about 1,016,703,396,069,942,173 X 10^-27 seconds to travel one foot. Fun little fact. I was bored so I did all the calculations from 186,282.4 mi/sec.

Here's the math if you are interested:
5280 = 1 foot in a mile
5280 X 186,282.4 = 983,571,072
1/983,571,072 ≈ 1,016,703,396,069,942,173 X 10^-27

or you could just round of to about 1.02. I tried to make it exact, but it seemed to be an irrational number.

You were bored and computed the speed of light in feet per second? I'm impressed. But you have made an error - 1/1,000,000,000 is 1 x 10^-9 (not -27) seconds

A long time ago my High School chemistry teacher [while covering units and conversions thereof] had us calculate the speed of light in furlongs/fortnight.
A furlong = 1/8 mile
fortnight = 14 days

I recall converting the stated number of [kilo]calories in a Big Mac into kWH, and getting a scary result

You got your exponent wrong. should be 10^-9.

I use this fact quite a bit in my work, but I use the fact that light travels 11.803 inches per nanosecond.

You are wrong genius that should be 10^-9

yup 10 -9 billy
