None of us has a handle on the Centigrade conversion but we 're all sure that it is at least 95 degrees here . We ' ve met K.C. and Phil , our hosts at the hotel , and they ' ve recommended a snorkle trip for us to take tomorrow .

Why does it matter they do n't have a handle on the centigrade conversion ?


They are traveling in a country that uses Celsius .
