Answer 1

Answer and Explanation:

40° Celsius is equal to 104° Fahrenheit.

Answer and Explanation:

Here we will show you how to convert 273 K to F so you know how hot or cold 273 degrees Kelvin is in Fahrenheit. The K to F formula is (K − 273.15) × 9/5 + 32 = F. When we enter 273 for K in the formula, we get (273 − 273.15) × 9/5 + 32 = F.

Answer and Explanation:

56 degrees Celsius is equal to 132.8 degrees Fahrenheit. To convert 56 degrees Celsius to Fahrenheit, substitute 56 for 'C' in the formula given. Multiply the fraction by 56.

Answer 2

Answer:

Here is a variant on Herbert's answer, using \dimexpr instead (inspired from the thread \ifnum for real numbers of comp.text.tex), which allows to do conversions in a purely expandable way. The syntax is \convertto{mm}{1pt} to convert 1pt in mm:

\makeatletter

\def\convertto#1#2{\strip@pt\dimexpr #2*65536/\number\dimexpr 1#1}

\makeatother

The results are not quite the same as with the printlen package, probably due to the fact that \dimexpr performs arithmetic slightly differently from TeX. Here's a table showing all the converted lengths (I omitted sp to avoid arithmetic overflows):
