Final answer:
The temperature data compiled by the meteorologist for the month of May is in degrees Celsius (°C).
Step-by-step explanation:
The unit of measurement for temperature in the provided data is °C (Celsius). The meteorologist compiled a list of temperatures specifically mentioning the use of degrees Celsius for the month of May. The three main temperature scales are Celsius, Fahrenheit, and Kelvin. These scales differ in their starting points and the size of their degrees. The Celsius scale is commonly used in science along with the Kelvin scale. Converting from Celsius to Fahrenheit involves the equation °F = (°C × 9/5) + 32, while converting from Fahrenheit to Celsius involves subtracting 32 and then dividing by 1.8. The Kelvin scale is related to Celsius by an offset; that is, K = °C + 273.15.
