So you want to convert between miles and kilometers. The conversion
factor is... uh... A 40-year-old calculator book provides a useful
tip: Unless you're designing a space probe, you can use ln(5).
WHAT?
Yes, the natural logrithm of 5 approximates the conversion factor
between miles and kilometers; specifically one mile is about ln(5)
kilometers. It's accurate to four digits.
If nothing else, it's faster to type on a calculator.
I think that's hysterical.
You do use Google search? Try typing '1 mile = ? kilometers' in the
google search bar. Answer = 1.60934.
P.S. The google search bar has come a long way. It can be the source of
a lot simple-ish maths solutions, thanks to rudimentary AI.
