How can you define temperature in terms of mass and length and time?

In: Physics [Edit categories]

Answer:

Fundamental units and unit analysis

All units can be decomposed into the fundamental units of mass, length, and time. Some would also add the fundamental unit of charge, which used to be the coulomb but is now, I think, the ampere¹.

For example, the watt is a joule per second; the joule is a newton-meter; the newton is a kilogram-meter squared per second squared². You will have to do a similar decomposition of a Kelvin (or a degree Celsius or Fahrenheit).

1. The ampere was once defined as one coulomb per second. But now I think the coulomb is defined as an ampere-second.

2. The unit of force is the newton, F = ma, and the units for acceleration are meters per second squared.
