The SI units for measuring different aspects of a solid are given below.
If you mean what SI units can be used to measure solids, they would be the meter for length, width, and height; the kilogram for mass; Kelvins for thermodynamic temperature; and the mole for the quantity of a substance.
These SI units can be converted into other measurements using the proper conversion factors. For example, the volume of a solid is determined by multiplying length, width, and height to give cubic meters,
There are many ways to convert measurements using conversion factors, such as
For example, the mass of an empty
