Example

Metric Measurement: Temperature Temperature is a measure of the kinetic energy of the atoms in an object. Temperature is measured with a thermometer and measured in Fahrenheit, Celsius or Kelvin. The Kelvin scale begins at absolute zero, or 0 K. At 0 Kelvin no more heat can be removed from an object. To convert to Kelvin you add 273 degrees to the Celsius reading. To convert degrees Celsius (°C) to degrees Fahrenheit (°F) multiply by 1.8 and then add 32.

Celsius temperature conversion formulae from Celsius to Celsius Fahrenheit [°F] = [°C] × 9⁄5 + 32 [°C] = ([°F] − 32) × 5⁄9 Kelvin [K] = [°C] + 273.15 [°C] = [K] − 273.15

Conversions Convert 60°C to Fahrenheit.

Fahrenheit temperature conversion formulae from Fahrenheit to Fahrenheit Celsius [°C] = ([°F] − 32) × 5⁄9 [°F] = [°C] × 9⁄5 + 32 Kelvin [K] = ([°F] + 459.67) × 5⁄9 [°F] = [K] × 9⁄5 − 459.67

Conversions Convert 68°F to Celsius.

Kelvin temperature conversion formulae from Kelvin to Kelvin Celsius [°C] = [K] − 273.15 [K] = [°C] + 273.15 Fahrenheit [°F] = [K] × 9⁄5 − 459.67 [K] = ([°F] + 459.67) × 5⁄9

Temperature relathionships (°F) = 9/5*(°C) +32 (°C) = 5/9*[(°F) –32] (°C) = (K) – 273.15
