ITC (International Temperature Scale)

The International Temperature Scale (ITS) is a standardized system used worldwide to measure temperature accurately. It provides key reference points, like the freezing and boiling points of water, and specifies how thermometers should be calibrated across different temperature ranges. This ensures consistent and reliable temperature readings for scientific, industrial, and everyday applications, regardless of location or device. The scale is continually refined using precise measurements and physical constants, allowing different thermometers to be compared and ensuring that temperature measurements are universally comparable and accurate.
