The metric units for temperature are degrees Celsius. There are no other units used. Temperature is one area where you may find it necessary to convert from Celsius to Fahrenheit and vice versa as you probably do not have two ovens or stoves at your disposal. However, many modern stoves and ovens, as well as most thermometers, have both Celsius and Fahrenheit temperatures marked on their controls.
Note: There are many “apps” available for converting measurements. These can easily be downloaded onto a smartphone or tablet and used in the kitchen.
