A

Calorie, Gram Calorie, Small Calorie

6
Q

A temperature scale in which 32dF represents the freezing point and 212dF the boiliding point of water under standard atmospheric pressure.

A

Fahreinheit Scale

when you know degrees Celsius, first mltiply by 9/5 and then add 32 to find degrees Fahrenheit.

7
Q

A temperature scale divided into 100 degrees, in which 0dC represents the freezing point and 100dC the boiling point of water under standard atmospheric pressure.

A

When you know degrees Fahrenheit first subtract 32 and then multiply by 5/9 to find degrees Celsius.
