METRIC MEASURES

In the previous class, we have learnt that metre, gram and litre are the standard units of
length, weight and capacity, respectively.
There are other units of metric measures (length, weight and capacity) to measure smaller

lengths, masses and capacities as well as to measure larger lengths, weights and capacities.
Metric measures Standard unit Units of metric measures used in daily life

Length metre km, m, cm, mm
Weight (mass) gram kg, g, mg
Capacity litre L, mL

We put different prefixes to the standard units of metric measures. The most commonly

used prefixes are ‘deca’, ‘kilo’ and ‘hecto’ for higher units and ‘deci’, ‘centi’ and ‘milli’ for
lower units.
There is a relationship among the various units of metric measures. Here, is a table below
that shows the relationship between different units of measurement and can be understood
using the place value chart.

Place thousands Hundreds tens Ones tenths Hundredths thousandths
Value (1000) (100) (10) (1) 1 1 1
