Temperature is a quantitative measure of the degree of heat present in a material. More specifically, temperature is the readout of internal thermal energy that an object holds, expressing the amount of vibration energy that is present among the atoms within that object. Temperature can be expressed as Celsius or Farenheit degrees (the conversion equation between these units is: T(°F) = T(°C) × 1.8 + 32). Because temperature affects every existing material, understanding and tracking temperature is particularly important in the field of metrology. Accurate measurement necessitates accounting for existing or potential temperature variation. Back to entire glossary
