Inches to cm

How units were defined in the past

Over decades units definitions have changed. In this article historical definitions review was done. Here is’t worth to mention that units were derived from the dimensions of the human body. For example, inch was the width of human thumb. A yard was invented by merchants for measuring linen. One yard was the length of the cloth stretched between the chin and the fingertips of an arm stretched out to the side.

Currently there is more that one system of measuring and it differs depending of county. Systems of measurement in use include the International System of Units or SI (the modern form of the metric system), the British imperial system and the United States customary system.

International system of measurement

Measurements of weights and measures such as length should generally be done in the same unit worldwide. For this purpose, an international system of units measuring was adopted during the General Conference of Measures in 1960. The abbreviation “SI” comes from the French name of this system, ie Le Système International d’Unités. In the SI methodology of units, the measure of length (base unit) is meter (m). SI prefixes are added before the unit. For example, the unit “km” includes the prefixes k (kilo, or 10 to the third power – a fraction of kilo) and m (one hundredth).

Metric units and centimeters cm conversion – conversion table

Before providing an information on how many centimeters are in kilometer or meter, it’s worth to provide centimeter definition. A centimeter (cm) is equal to one hundredth of a meter. In the SI logic an abbreviation for centimeter is cm. Centimeter (cm) is also equal 10 millimeters. More information such as meter definition and other can be found here.

1 kilometer (km) = 1000 meters (m) = 100000 centimeters (cm)

1 meter (m) = 100 centimeters (cm)

1 centimeter = 10 millimeters (mm)

Easy calculation for meters and centimeters converter

When we use centimeters and other values such as meters or kilometers, we can base on simple calculation, which was described in one of our articles. This conversion method is used in most countries. Conversion factor for decimal values is 10, 100, 1000, 10000 respectively. That logic can be applied when converting a larger unit to a smaller one. In that case we multiply a value by 10 or bigger 10 multiplication. As that logic was explained in details, in this article we can present SI length values conversions into 1 cm.

1 cm = 10 mm

1 cm = 0.01 m

1 cm = 0.00001 km

Inch value and other values

In our web site there are few articles introducing how inch is defined. We will base on some information provided in that article.

Inch (inch symbol: in) is an off-system unit of measurement of length initially corresponding to three times the length of an average barley grain. One of the so-called imperial units. It is one twelfth of a foot. Since adoption of the International Yard and Pound Agreement in the 1959 one inch conversion into centimeter is exactly 2.54 cm.

The foot (or feet; symbol: ft) is a unit of length in the British and United States customary systems of measuring. Since the International Agreement of 1959, one feet is approximately equivalent of distance 0.3048 meters exactly.

The yard (symbol: yd) is an English unit of length in both the British imperial and American systems of measuring equalling 3 foot or 36 inches.

Miles can be divided into the two most common types in use today, namely land miles and nautical miles. According to international standard unit land mile is approximately 1.609 km, which is equivalent to 1609 meters. The nautical mile is slightly longer, converted to kilometers it is equal to 1.852 km, which corresponds to distance equal 1852 m.

To sum up:

1 inch is equal 2.54 centimeters

1 centimeter is equal 0.3937007874 inch

1 ft = 12 inches

1 ft = 30.48 centimeters

1 inch = 0.08333 ft

1 centimeter = 0.03280839895 ft

1 yd = 36 inches

1 yard = 91.44 centimeters

1 centimeter = 0.010936132983 yd

1 inch = 0.02777 yd

1 mile = 63360 inches

1 mile = 160934.4 centimeters

1 inch = 0.000015782828283 miles

Simple multiplication can be used to convert numerous inches and centimeters to different units.

Centimeters converter

Different conversions are needed sometimes when a base value is centimeter (cm). Although many everyday measurements in Great Britain are provided in inches someone may wonder how many centimeters other units contain. In this article we did that analysis so you can check it. Just to give some examples:

1 cm = 0.39 inch

1 cm = 0.010936132983 yard

1 cm = 0.032808398949 feet (foot)

1 cm = 0.0000062137119224 mile

Cm converter inches – different standards. How to convert inches?

In this web you can find some examples where we convert inches. In countries where British length measuring method is used, many people know some simple conversions by heart. Many people commonly use online converters. Such web converters provide defined values for one unit, for example for one inch and it’s easy to convert inch to cm or other unit.

Convert inches to cm

1 inch = 2.54 cm

2 inches = 5.08 cm

3 inches = 7.62 cm

4 inches = 10.16 cm

5 inches = 12.7 cm

6 inches = 15.24 cm

Inches to cm

People who plan to buy a new TV pay special attention to the size of the screen. As you know, the bigger, the better – although this is not really true – for example a TV set for a child does not have to be big. Unfortunately, not everyone knows how to measure inches. As a result, it is difficult for them to determine what the screen size will be, especially for online purchases. Well, to measure inches for a TV set, multiply the number of inches provided by the manufacturer by 2.54. In this portal we presented how to convert inches when considering buying a television. Here we present additional conversion summary.

The sizes of the TVs are as follows (inches to cm):

if the TV is 32 inches, the screen diagonal will be 81.28 cm,

if the TV is 40 inches, the screen diagonal will be 101.6 cm,

if the TV is 42 inches, the screen diagonal will be 106.68 cm,

if the TV is 55 inches, the screen diagonal will be 139.7 cm,

if the TV is 60 inches, the screen diagonal will be 152.4 cm,

if the TV is 65 inches, the screen diagonal will be 165.1 cm,

if the TV is 70 inches, the screen diagonal will be 177.8 cm,

if the TV is 75 inches, the screen diagonal will be 190.5 cm,

if the TV is 86 inches, the screen size will be 218.4 cm.

As you can see, if you decide on a huge 86-inch TV, the screen diagonal will be over two meters – which is really a lot! It’s definitely a good idea to measure the inches of your TV set before you buy it so that it doesn’t turn out that the TV will be too small or, on the contrary, that the huge screen will overwhelm the room. You also need to remember about the height at which the TV screen should be so that not watching programs is fully comfortable.
