Question

Why do scientists prefer the SI units over the old English system of measurement?

Answer 1

The old English system of measurement is known as the imperial system of measurement. This system of measurement was used until 1824 and after that the SI system of measurement was used by the scientists. This SI system came in 1965.

Complete step by step answer:
The international system of measurement is known as the SI system of measurement. This is also known as the metric system of measurement. The SI is made up of 7 base units that define the 22 derived units with special names and symbols. The seven basic units of measurement in the SI system are:
(1 Mass- the SI unit of mass is kilogram.
(2)Length- the SI unit of length is metre.
(3)Time- the SI unit of time is second.
(4)Temperature- the SI unit of temperature is Kelvin.
(5)Amount of a substance- the SI unit of amount of a substance is mole.
(6)Electric current- the SI unit of electric current is ampere.
(7)Luminous intensity- the SI unit of luminous intensity is candela.
The reason why the scientists prefer the SI units over the old English system of measurement are:
(A) The SI system of units uses 10 as the base, which is also used in our number system. So, it is easy to learn, remember and understand.
(B) Another factor which supports the SI unit of measurement is that the Sl units are interrelated in such a way that one unit is derived from other units without conversion factors.
(C) The most important factor in favour of SI units is that the SI system of units is used all over the world. So, it allows scientists from different regions of the world to use a single standard in communicating scientific data without any vocabulary confusion.

Note: Still there are countries which use the old English system of measurement instead of the SI system of measurement. The three major countries which use the old English system of measurement or the imperial system of measurement are U.S., Liberia and Myanmar.
