Measurements From Smallest To Largest

Metric Units of Length

From smallest to largest, the metric units of length are millimetres (mm), centimetres (cm), metres (chiliad) and kilometres (km). There are 10 mm in i cm, 100 cm in 1 m and 1000 m in 1 km. The metric units of length are used in all countries except the USA, Liberia and Myanmar.

Here is a table showing the most common metric units of length and how to convert between them.

To convert between metric units of length, employ the following rules:

• To convert cm to mm, multiply past 10.
• To convert m to cm, multiply by 100.
• To convert km to g, multiply by yard.
• To catechumen mm to cm, divide by 10.
• To catechumen cm to m, split by 100.
• To convert k to km, divide past 1000.

Here are some examples of converting between metric units:

Original Metric Unit	Conversion	Equivalent Metric Unit
20 mm	÷ 10	2 cm
36 mm	÷ x	3.half dozen cm
200 cm	÷ 100	2 m
518 cm	÷ 100	v.18 m
5000 chiliad	÷ chiliad	5 km
7200 thousand	÷ g	vii.ii km
eight km	× 1000	8000 m
6.iii km	× 1000	6300 grand
five m	× 100	500 cm
three.four 1000	× 100	340 cm
nine cm	× ten	ninety mm
vi.5 cm	× 10	65 cm
3 km	× 100 000	300 000 cm
ii.5 m	× k	2500 mm

Imperial Units of Length

From smallest to largest, the most common imperial units of length are inches (in), yards (yd), feet (ft) and miles (mi). There are 12 inches in a foot, three anxiety in a chiliad and 1760 yards in a mile. Imperial units of length are used in the USA, Liberia and Myanmar.

Hither is a table showing the nigh common majestic units of length and how to convert between them.

To convert between metric units of length, employ the following rules:

• To convert feet to inches, multiply by 12.
• To convert yards to anxiety, multiply by 3.
• To catechumen miles to yards, multiply by 1760.
• To convert inches to feet, split past 12.
• To convert feet to yards, split by 3.
• To convert yards to miles, divide by 1760.

What is the Difference Between Metric and Imperial Units?

Metric units utilise base ten conversions, whereas royal units exercise non. This means that it is easier to convert betwixt metric units by multiplying or dividing by 10, 100 or 1000.

Metric units have a consistent conversion ratio across different measurements whereas purple units practise non. This makes it easier to remember and work with metric units. For case, to convert from kilometres to metres, we multiply past 1000 and to convert from kilograms to grams, nosotros likewise multiply by 1000. We do not accept similar patterns with royal units such as inches to feet or ounces to pounds, which can make it more challenging to work with these units.

Metric units are used consistently in nigh countries throughout the world. Only America, Libera and Myanmar officially use imperial units. These countries nonetheless use these traditional imperial units because they have been working with imperial units for many years and it would be plush to convert everything into metric units.

Although similar in size, a metre is non the aforementioned length as a 1000. i k is equal to 1.09 yards and and so, 1 metre is longer than 1 m by approximately 3 inches or 8 centimetres.

A centimetre is smaller than an inch. A centimetre is less than half the size of an inch. 1 inch is approximately equal to 2.5 centimetres.

Units of Length List

The virtually common units for length are shown in the list beneath with examples:

Metric Units of Length	Case	Conversion
1 millimetre (mm)	Thickness of a staple	10 mm = i cm
1 centimetre (cm)	The width of a little finger	100 cm = 1 m
ane metre (1000)	The width of a doorway	thousand m = one km
1 kilometre (km)	Roads are measured in kilometres	1000 m = 1 km
Imperial Units of Length	Example	Conversion
1 inch	The size of television screens	12 inches = i foot
1 foot	People's pinnacle	3 feet = 1 yard
1 1000	The size of rooms or buildings	1760 yards = one mile
1 mile	The distance between cities	1760 yards = 1 mile

Other less ordinarily used units of length are nanometres and micrometres. These units of length are used to mensurate incredibly small distances equally seen under a microscope.

In imperial units, 1 m is one thousandth of i inch. yard thous brand up 1 inch.

3 miles is called 1 league.

How to Choose an Appropriate Unit of Length

From smallest to largest, the common units of length are millimetres, centimetres, metres and kilometres.

Millimetres are typically used to measure very pocket-sized objects, such equally objects you can concur in your closed paw. Centimetres are typically used to measure objects that are shorter than the width of a door. Metres are typically used to measure out objects that are longer than the width of a door. Kilometres are used to measure out the distances betwixt towns, cities or countries.

Here is an instance of measuring a seed in millimetres. The seed is 8 mm long and it is less than 1 cm.

Nosotros know that millimeters would be an advisable choice of unit to measure this seed because the seed is non fifty-fifty one centimetre long.

Information technology is e'er possible to apply a smaller unit than is typically used. This may be done to mensurate something to a greater caste of accurateness.

For case, a phone screen is large enough to be measured in centimetres only its size might exist given in millimetres for a greater level of accuracy.

Here is an instance of measuring a pencil in centimetres. The pencil is 12 cm long.

If an object can be measured well with a ruler, centimetres are a good choice of unit.

Information technology is easier to say 12 cm than 120 mm. The next unit up after centimetres is metres and this pencil is not fifty-fifty 1 metre long.

Metres are a typical unit of length chosen to measure the size of buildings. Below is an example of measuring the size of a house in metres.

Distances between towns, cities and countries are always measured in kilometres.

For instance, the distance between the two cities of London and Manchester is approximately 300 km.

Here are some examples of selecting the almost appropriate unit of measurement:

Object	Most advisable unit of measurement	Actual measurement
The length of a grain of rice	Millimetres	seven mm
A blueberry	Millimetres	12 mm
An eraser	Millimetres or centimetres	45 mm or 4.five cm
An apple	Centimetres	10 cm
An A4 page	Centimetres	29.vii cm
A man	Centimetres or metres	180 cm or ane.8 m
A passenger vehicle	Metres	12 g
The height of a skyscraper	Metres	150 grand
The distance between the UK and the USA	Kilometres	7000 km

Examples of Objects 1 mm Long

A millimetre is the smallest measurement that can be fabricated using a ruler.

The size of a millimetre is shown below.

Some examples of objects 1 mm long are:

• The width of a staple
• The width of a precipitous pencil tip
• The thickness of a piece of card
• The thickness of a bank carte
• The width of a poppy seed

Examples of Objects 1 cm Long

A centimetre is about the width of a little finger. It is the distance between the large numbers on a ruler.

Some examples of objects ane cm long are:

• The width of your fiddling finger
• The length of a staple
• The width of a pea
• The thickness of notepad
• The length of a coffee bean

Examples of Objects ane yard Long

Some examples of objects 1 thou long are:

• The length of a baseball bat
• The length of a staple
• The height of a door handle from the footing
• The elevation of a person'south hips from the basis
• The lengths of a guitar
• The largest step y'all tin can brand

A metre is well-nigh as alpine every bit a modest child. However a fully grown adult may be but beneath 2 metres tall.

Examples of Things that are ane km Long

Some examples of things that are i km long are:

• The Aureate Gate Span
• The distance walked in fifteen minutes
• The earth'south tallest skyscrapers
