Measurement is integral to physics and all scientific subjects. Kids compare attributes like height and toy amounts before learning math, showing measurement is innate. The International System of Units defines seven base units including the meter, kilogram, and second. The standard meter is defined as a specific number of wavelengths of orange-red light in a vacuum. The standard kilogram is a platinum-iridium cylinder kept by the International Bureau of Weights and Measures. The second is defined as a specific number of periods of radiation from a cesium atom.

1. Definition of Measurement in Physics
Measurement is integral part of Physics like any other scientific
subject. Measurement is a integral part of human race, without it
there will be no trade, no statics. You can see the philosophy of
measurement in little kids who don't even know what math is.
3. Kids try to compare their height, size of candy, size of dolls
and amount of toys they have. All these happen even before
they know math. Math is built into our brains even before we
start to learn it.Math provides a great way to study about
anything, that's why we see computers involved in almost
anything because they are good at math.

A. The International System of Units
Since the 14th General Confrence on Weights and Measures
(1971), selected as base units the seven quantities. Thats what
we call as.

B. The Standard of Length
The first International Standar of length was a bar of a
platinium-iridium alloy called the standard meter
Specifically 1 meter is now defined to be 1.650.763,73
wavelengths of particular orange-red radiation in a vacuum
condition.

The SI standard of mass is a platinum-iridium cylinder kept at
International Bureau of Weights and Measures as a mass of 1 kg.

C. The Standard of Time
Exactly, the measurement of time has two aspects. For civil and
for some scientific purposes.
In 1967 the second based on the cesium clock was adopted as
an International standard by the 13th General Conference on
Weights and Measures. The second was defined as
9.192.631.770 periods of particular Cs transition selected.
