my solution
Write a function convert_temp(temp, from_scale, to_scale) converting temperature from one scale to another. Return converted temp value.
Round converted temp value to an integer(!).
Reading: http://en.wikipedia.org/wiki/Conversion_of_units_of_temperature
possible scale inputs:
"C" for Celsius
"F" for Fahrenheit
"K" for Kelvin
"R" for Rankine
"De" for Delisle
"N" for Newton
"Re" for Réaumur
"Ro" for Rømer
temp is a number, from_scale and to_scale are strings.
convert_temp( 100, "C", "F") # => 212
convert_temp( 40, "Re", "C") # => 50
convert_temp( 60, "De", "F") # => 140
convert_temp(373.15, "K", "N") # => 33
convert_temp( 666, "K", "K") # => 666
