6.7.You will need to google each in turn for your essay, sorry.......
Need to write a 500 word essay on the 7 SI units and what the standards are based on for physics class. I know what the 7 are, but I'm stuck on what they are based on.

In order left to right of Quantity, Name, Symbol :
1. length = the metre, m
2. mass = the kilogram, kg
3. time = the second, s
4. electric current = the Ampere A
5. thermodynamic temperature = degrees Kelvin K
6. amount of substance = the mole mol
7. luminous intensity = the candela cd

You will need to google each in turn for your essay, sorry.
