Case Study Questions
The names of temperature scales, the Celsius scale, the Fahrenheit scale, and the Kelvin scale start with a capital letter. For the units for temperature, degree Celsius and degree Fahrenheit, the word degree starts with a lower-case letter while Celsius and Fahrenheit start with a capital letter. The unit kelvin starts with a lower-case letter. The symbols of all units (°C, °F, K) are capital letters. Note that the degree sign (°) is not written with K. A full stop is not written after the symbol, except at the end of a sentence. While writing the temperature, a space is left between the number and the unit. For temperatures more than one degree, use the plural of ‘degree’, that is, ‘degrees’, while writing the full form of the unit.
