Temperature measurement.

A temperature of absolute zero is called 0 K on the kelvin scale and −273.15 °C on the Celsius scale, therefore a translation factor of −273 °C is needed. So we're basically multiplying by one, which is the same as doing nothing, and subtracting 273. The reverse conversion is equally simple. °C ← K. RTDs are more stable than thermocouples. On the other hand, as a class, their temperature range is not as broad: RTDs operate from about -250 to 850°C whereas thermocouples range from about -270 to 2,300°C. Thermistors have a more restrictive span, being commonly used between -40 and 150°C, but offer high accuracy in that range.Watch this video to find out whether or not to use paint that has been stored outside in freezing temperatures.
