What is the unit of measurement for temperature in the metric system?

The unit of measurement for temperature in the metric system is Celsius. Celsius is widely used for everyday temperature measurements, particularly in contexts such as weather reporting and cooking. It is part of the metric system, which is based on units that are interoperable and decimal-based, making it easier to convert between different measures.

The Celsius scale sets the freezing point of water at 0 degrees and the boiling point at 100 degrees under standard atmospheric conditions, which makes it intuitive for daily usage. Although Kelvin is also a unit of temperature and is part of the SI (International System of Units), it is primarily used in scientific contexts, particularly in physics and chemistry, where absolute temperature measurement is essential. Kelvin is based on the absolute zero benchmark where all molecular motion ceases.

Joules, on the other hand, is a unit of energy and not directly related to the measurement of temperature. Fahrenheit is a temperature scale that is used primarily in the United States and a few other countries, but it is not part of the metric system.

Thus, Celsius is the more universally recognized metric unit for temperature in day-to-day applications, aligning with the typical understanding of temperature measurement in the metric system.
