yes no maybe so
The meter its a measurement unit that was first introduced by the French in 1790.

Oliver B. Shallenberger received a patent for the first electricity meter in 1888. There were meters that were invented in the early 1880s, including one by Edison around 1882.
A square meter is a derived unit because it is a unit of measurement that is calculated by multiplying two one-dimensional units (meters) together to represent a two-dimensional area. It does not have a unique physical definition but is derived from the fundamental unit of length.
If you use meters for length, then the derived unit is the square meter.
In the SI, the square meter is derived from the meter (meter x meter). But in general, which units are derived and which are base units really depends on the system of measurement chosen. You could define a unit of area as a base unit, and derive a length as the square root of that - although I don't think any serious system of units has actually done that so far.

It means that it is defined on the basis of other units. For example, in the SI, the meter and the second are two of the seven "base units"; the unit for area is the square meter (meter x meter), so it is a DERIVED unit; so is the unit for speed, meters / second.
The meter is the metric base unit for volume, and the cubic meter is the derived unit.
Square meter, cubic meter, diopter (= 1/meter). Then, of course, there are derived units that include the meter together with other units - this can be said of most SI units - such as meter/second (for speed), meter/second2 (for acceleration), newton for force (mass x acceleration), work or energy (force x distance), etc.
Mass: kilogram Length: meter Volume: cubic meter (this is not a base unit, since it is derived from the meter)
In the SI measurement system, a meter is a "base unit". However, the definition relies on the prior definition of the second.
The derived unit of pressure in the International System of Units (SI) is the Pascal (Pa). It is defined as one Newton per square meter (N/m²).
m can mean milli or 10-3 and as such is a multiplier not a unit m = mass (kg) or other is a fundamental and not a derived unit M = moles is a fundamental unit m = meter is a fundamental unit and not derived
