STANDARDS OF LENGTH, MASS, AND
TIME
To communicate the result of a measurement of a certain physical quantity, a
unit for the quantity must be defined.
For example,
length is defined to be 1.0 meter, a wall is 2.0 meters high, we know that the
height of the wall is twice the fundamental unit of length.
Likewise, if our fundamental unit of mass is defined as 1.0 kilogram, and we
are told that a person has a mass of 75 kilograms, then that person has a
mass 75 times as great as the fundamental unit of mass.
In 1960, an international committee agreed on a standard system of units for
the fundamental quantities of science, called SI (Syst&egrave;me International). Its
units of length, mass, and time are the meter, kilogram, and second,
respectively.

One ten-million of the distance

the official length of the meter either
In 1960,

this definition was abandoned also
This standard was abandoned
for several reasons
 In October1983, the meter was redefined as

the distance traveled by light in vacuum during a time interval
of 1/299 792 458 second. This latest definition establishes the
speed of light at 299 792 458 meters per second
.
Mass
Definition of the kilogram
The SI unit of mass, the kilogram, is defined as the mass of a

specific platinum-iridium alloy cylinder kept at the International
Bureau of Weights and Measures at S&egrave;vres, France
Definition of mass at high velocity

mass is a quantity used to measure the resistance to
a change in the motion of an object. It’s more
difficult to cause a change in the motion of an object
with a large mass than an object with a small mass.

When dealing with atoms and molecules, we usually use
the (atomic mass unit)
1 u = 1.6605 *10^-27 kg

Time
Definition of the second
the second, was defined to be (1/60)(1/60)(1/24)
1/86 400 of the average solar day.

This standard was abandoned for
several reasons

The second is now defined as 9 192 631 700 times the
period of oscillation of radiation from the cesium atom.

Physical quantities can be
divided into two
categories:
Base quantities (base
unit ) and derived
quantities (derived unit).
