Yes indeed. One needs a new unit of measurement when the subject being considered cannot be measured in terms of the existing units, OR when it is more convenient to use a new scale.
In practice we need a new unit of measure when we need to measure Height and we only have Length so far. Conveniently, the scalar (the actual scale measure) can be the same.
OK until we meet Time, which we cannot measure in terms of length, height and width. So our new unit is the second - with its definition.
And when we come to measure Temperature (oC), or Sound Level (dB), Intellectual Quotient (IQ), ... ... we have to use more convenient or new units.
Metric units of measurement are more fun to say.
SI units are defined for physical measurements, like measurements of mass, length, etc. - there are no specific SI units for plain numbers.SI units are defined for physical measurements, like measurements of mass, length, etc. - there are no specific SI units for plain numbers.SI units are defined for physical measurements, like measurements of mass, length, etc. - there are no specific SI units for plain numbers.SI units are defined for physical measurements, like measurements of mass, length, etc. - there are no specific SI units for plain numbers.
To do math.
There are exactley 7 units of measurements
The system of units used for measurements in chemistry is called the International System of Units (SI). It is a globally recognized system that provides a consistent set of units for measuring physical quantities.

Standard units are more commonly used than non standard units. Also, many of the conversion factors, such as the Universal Gravitational Constant or the Speed of Light, are in standard units and, if your measurements were not in appropriate units, you would need to convert.
To accurately convert and translate measurements between different units, you need to understand the conversion factors between the units. Use conversion tables or formulas to make the necessary calculations. Practice and double-check your work to ensure accuracy.
By unit of length and mass and conversion ,we can say that units of measurements in length are meters ,cm ,dm ,dam ,hm.
