But they, too, tend to be esoteric, with temperatures, for instance, always given in the Celsius scale.

Much of the world uses the Celsius scale ( C) for most temperature measurements.

The following table shows the temperature conversion formulas for conversions to and from the Celsius scale.

This problem is apparently why the freezing point of water is not used to define the Celsius scale anymore.

On the Celsius scale, the freezing and boiling points of water are 100 degrees apart.

The Celsius scale of temperature is not absolute since negative values are possible.

Temperatures can be converted from the Celsius scale to the absolute scale by adding 273.15.

Some key temperatures relating the Celsius scale to other temperature scales are shown in the table below.

Most of the entire scientific field and many engineering fields use the Celsius scale, and the metric system in general.

On the Celsius scale, 100 degrees is the boiling temperature of pure water at sea level.
