Temperature Conversions

Temperature Scales Fahrenheit – Scale in which 32°F represents freezing/melting and 212°F represents boiling for water. Celsius – Scale in which 0°C represents freezing/melting and 100°C represents boiling for water. Kelvin – Absolute zero scale in which 0 K represents the temperature at which all molecular movement stops.

Temperature Conversion Equations 4 equations to use: oF = 9/5oC + 32 oC = 5/9 (oF-32) K = oC + 273 oC = K – 273

Helpful Hints Identify the equation needed. Plug in the numbers to solve Remember the math rules: Solve what is in parenthesis first Solve Multiplication & Division before addition and subtraction Show all work Put box around final answer

Practice Problem #1 240oC = ____K K = oC + 273 K = 240 + 273 K = 513

Practice Problem #2 50oF = ____ oC oC = 5/9 (oF-32) oC = 5/9 (50-32)

Practice Problem #3 510K = ____ oC oC = K – 273 oC = 510 – 273

Practice Problem #4 20 oC = ____ oF oF = 9/5oC + 32 oF = 9/5(20) + 32
