Table wouldn't work. You don't have the imperial:metric case, where one would simply apply a factor (or divisor, in the other direction) and get a number. In several cases you get two numbers on the imperial side - six stone four pounds, five feet two inches, six inch and 3/8 (which they write with a minus sign between but it's not really a subtraction, it's addition). Only Celsius (of whom they never heard, they think the guy's name was Centigrade) vs Fahrenheit is simple.
