Answer
The 7 SI Fundamental (Base) Units:
| Unit | Symbol | Quantity |
|---|---|---|
| Metre | m | Length |
| Kilogram | kg | Mass |
| Second | s | Time |
| Ampere | A | Electric current |
| Kelvin | K | Temperature |
| Mole | mol | Amount of substance |
| Candela | cd | Luminous intensity |
Newton, Joule, and Watt are derived units, not fundamental. Kilogram, metre, and second are the fundamental units most directly used to describe a physical body.
