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.

Measurement of Physics

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. That’s what we call as….

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 Mass


Neraca is an intrument that used for measure the mass of something,

While balance of sheet, Ohause balance, and digital balance are used for high level of careful


Exactly, the measurement of time has two aspects. For civil and for some scientific purposes.

C. The Standard of Time

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.

Instruments of Time Measure


A showing of stopwatch shows 30 s (tergantung alat), every a second devided into 10 scale, a showing of the short pointer shows 15 minutes
