Primitive units of measurements are fundamental and indivisible units used to quantify physical quantities. Examples include the meter for length, second for time, kilogram for mass, ampere for electric current, kelvin for temperature, mole for amount of substance, and candela for luminous intensity.
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.
There are 1000 measurements in a kilogram.
I use metric units, such as meters, kilograms, and liters for measurements.
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.
Standard units were established to ensure consistency and accuracy in measurements. By having universally accepted units, people across different regions and disciplines can communicate effectively and compare measurements. Standard units also help to avoid confusion and errors when conducting scientific experiments or trade.
