a. cm
d. SCC
Further explanation
7 main quantities have been determined based on international standards,
- 1. Length, meters (m)
- 2. Time, second (s)
- 3. Mass, kilograms (kg)
- 4. Temperature, kelvin (K)
- 5. Light intensity, candela (cd)
- 6. Electric current, ampere (A)
- 7. Amount of substance, mol (m)
So the following not a base SI unit
a. cm
cm = 10⁻² m
the SI derived unit of length
d. scc
1 scc(standard cubic centimeter0 = 0.101325 J
the SI derived unit of energy.
