Final answer:
The Celsius scale is used instead of other centigrade scales because it is widely adopted in scientific contexts. It sets the freezing point of water at 0°C and the boiling point at 100°C. The Kelvin scale is also used in scientific work as an absolute temperature scale.
Step-by-step explanation:
The Celsius scale is used instead of other centigrade scales because it is widely adopted in scientific contexts and is the scale of choice for nonscience contexts in almost all areas of the world. The Celsius scale, also known as the centigrade scale, was named after Swedish astronomer Anders Celsius. It sets the freezing point of water at 0°C and the boiling point at 100°C, with 100 equal intervals between these two points.
The Celsius scale is more commonly used than the Fahrenheit scale in science because it is a metric scale that aligns with the International System of Units (SI). The Celsius scale is also easier to work with in scientific calculations and conversions. The Fahrenheit scale is still used in the United States and a few other countries, but it is less prevalent in scientific work.
In addition, the Kelvin scale is used in scientific work as an absolute temperature scale. It is closely related to the Celsius scale, with the freezing point of water at 273.15 K and the boiling point at 373.15 K. The Kelvin scale is preferred for scientific calculations involving gases and other absolute temperature-related phenomena.
