"Mental people are the most fun to be with. Fun-da-mental" - Albert Einstein

There are seven fundamental quantities. They are

  1. Length

  2. Mass

  3. Time

  4. Temperature

  5. Electric Current

  6. Luminous Intensity

  7. Amount of substance

All of them have their own S.I. units

To make everything simple, I like to measure all temperatures in Kelvin. Kelvin - 273.15 is Celsius. About 300 Kelvin is ideal temperature in a day (26.85 Degree Celsius)
