Measuring Instruments For Length And Mass

It is equal to the length of an average foot formerly 11 1 42 inches but now 12 inches.

Measuring instruments for length and mass.

This unit differed from place to place and trade to trade. All the substances around us can be measured by using various units like the mass of gold length of clothes the quantity of milk etc. Standard international si unit for measurement of length is meter. This is used by those needing a flexible instrument with which to measure length such as a tailor or anyone measuring the circumference of an object.

Length and mass introduction source. The use of the word measure in the sense of a measuring instrument only survives in the phrase tape measure an instrument that can be used to measure but cannot be used to draw straight lines. Various measuring instruments of length mass and time can be seen as follows. Determining mass means determining the amount of matter in an object of interest.

In general there are three most measured magnitudes in the world of physics for high school level namely length mass and time and dimension. These include balances scales newtonian based measurement devices measurement transducers vibrating tube mass sensors and the use of gravitational interaction. When we measure the distance between any two points in terms of width thickness depth and height we measure length. The standard instruments used nowadays to measure a length are ruler meter scale measuring tape vernier caliper and screw gauge.

Those quantities which can be measured is known as physical quantities like length mass etc. In this video we will learn how to take measurements of length using a meter stick volume using a graduated cylinder and mass using a digital scale. Measuring tapes come in two varieties. The most natural way to measure length is to compare it to some part of the body and for centuries people did just that the unit we call a foot has been used since ancient times.
