It was used to measure the strength of a laser. In the 1960s, razor blades were pretty much similar in shape and a Gillette was a non-standard unit for measuring the strength of a laser beam. The measurement comprised the number of laser blades that a laser device could burn through.
A coulomb is a unit for measurement of electrical charge and an ampere is the unit used for measurement of electric current.
you can measure the unit of a current in amps (A) we measure the current using a ammeter

You can invent any number of nonstandard units, but none of them is "best". It is best to use standard units, that is, the meter.

As far as I am aware, CO is not a unit of measure.
The unit used for measure temperature is the kelvin
Which unit of measure matches RAM
A unit can be a measure of length. It is one-dimensional. A squared unit can be a measure of area. It is two-dimensional. A cubic unit can be a measure of volume. It is three-dimensional.
This depends on what unit you are using to measure in. However, area will always be measure in (unit)^2.
