Units Of Length Conversion Charts


The metric system can be defined as a system of measurement that uses the litre, metre, and gram as base units of metric length (distance), capacity (volume), & weight (mass) respectively.

To measure larger or smaller quantities, we use units derived from the metric units.

The units khổng lồ the right of the base are lesser than the base unit. As we move lớn the right, each unit is ten times smaller or one-tenth of the unit to its left. So, the word ‘deci’ means one-tenth of the base unit, ‘centi’ is one-tenth of ‘deci’ or one-hundredth of the base unit and ‘milli’ is one-tenth of ‘centi’ or one-thousandth of the base unit.

The units lớn the left of the base unit are larger than the base unit. As we move khổng lồ the left side, each unit is 10 times greater than the unit to lớn its right side. So, a ‘deca’ means 10 times of the base unit, ‘hecto’ is ten times of ‘deca’ or hundred times of the base unit and ‘killo’ is ten times of ‘hecto’ or thousand times of the base unit.




Base Unit











So, the units for metric length, capacity(volume), and weight (mass) in the metric system are:

Metric Length: Centimeter (cm), Millimeter (mm), Meter (m), Decimeter (dm), & Kilometer (km) are used lớn measure how wide or long, or tall an object is.

What is the say mê Unit of Metric Length?

In the metric system, the si mê unit of length is a meter which is defined as follows:

“The metric length of the path that is travelled by light in a vaccum within 1⁄299792458 seconds”.

Some of the other units also include:







For understanding how big the metric units are, look at the table below:




The thickness of a credit thẻ or a plastic id card is about a millimetre thick


A fingernail is about a centimetre wide


A guitar is a meter long


The distance between cities is measured in kilometres

Other Non-SI Metric Length Units

If we take a look at the Imperial & U.S. Customary systems, then the basic unit of metric length is the yard. Some other units include:

Thou (1⁄1000 of an inch)

Line (1⁄12 of an inch)

Inch (25.4 mm)

Foot (12 inches, 0.3048 m)

Measure of Metric Lengths

10 millimeters (mm) =

1 centimeter (cm)

10 centimeters (cm) =

1 decimeter (dm) = 100 millimeters

100 centimeter(cm) =

1 meter (m) = 1,000 millimeters

1000 meters (m) =

1 kilometer (km)

Examples include measuring the thickness or metric length of cloth, a debit card, or distance between 2 cities.

Kilometer (km) (Kiran)


Hectometer (hm) (Had)


Decameter (dam) (Drawn)


Meter (m) (Many)


Decimeter (dm) (Different)


Centimeter (cm) (Colourful)


Millimeter (mm) (Masks)


Converting Larger Units khổng lồ Smaller Units

1 centimeter = 10 millimeters

1 meter = 100 centimeters

1 meter = 1,000 millimeters

1 kilometer = 1,000 meters

To Convert bigger units khổng lồ smaller units we multiply the number of large units by the conversion factor for the appropriate smaller units.

As 1 km = 1000 m

Therefore, 5 km equals 5 × 1000 equals 5000 m.

Example 2: How vày you Convert m lớn cm and mm?

In this activity, you will convert between metric units of metric length: kilometres, metres, centimetres, và millimetres.

1 km = 1000 m

1 m = 100 cm

1 m = 1000 mm

1 cm = 10 mm

Why Must Students Know About the Metric System?

The Metric System is important as without it, we would be completely confused about the units. It is completely scientific & has repeatable standards of measurement. It uses units like meter, litre và gram so as to lớn measure length, liquid, volume and mass. Students will need lớn know about the Metric System so as to understand all the different concepts that will be applicable in Math và the Science subjects. Having a standard system of measurement is the only way lớn go when measuring things as that clears all the confusions.

Fun Facts

A tonne is 1,000 kilograms.

The metric system had its beginnings back in 1670 by a mathematician called Gabriel Mouton.

Since the 1960s the metric system has been known as the "International System of Units" or "SI" (from the French "Système International").

The prefixes of the metric system can be remembered with the help of the mnemonic “King Henry Died of Drinking Cold Milk”.

There are various units greater than the kilo as well. These have prefixes mega, giga and tera. A mega is 1000 times a kilogram. A giga is thousand times mega và a tera is a thousand times giga.
