Can Kelvin Have Decimals?

Use the significant figures associated with the temperature in Kelvin. Recall that when adding/subtracting numbers, you don't round sig figs, but rather, just round to the least accurate decimal place. So 25°C becomes 298 K with three significant figures, since 25 + 273.15 should be rounded to no decimal places.

Can a temperature have a decimal?

DECIMAL PLACES WITHIN TEMPERATURES. Typically, temperatures in the current weather conditions are given in whole numbers. ... Both temperature scales can be made to have about the same precision if Fahrenheit is reported in whole degrees while Celsius temperatures are given to ½ degree increments (i.e. 12.5 C).
