Divide the number of centimetres by the conversion factor. Metres are larger than centimetres so the number of centimetres will be larger than the number of metres. It is not always easy to decide whether to divide or multiply by the conversion factor. There are 10 millimetres in a centimetre. Calculate the height of the sunflower in metres and millimetres. These can be used to convert the units used to measure length. The most common metric unit conversions for length are: mass in pounds (lb), ounces (oz) and stones.The imperial system uses the following units: The metric system uses three main units for measuring: Unit conversion tables like the above can be useful if for some reason you don't have access to an online converter.There are two systems used for measuring quantities - metric and imperial. Miles to km conversion table miles to km conversion table miles Solution:Īs you can see in certain scenarios the conversion is quite easy to do by doing the math by hand, but in others a unit converter is definitely necessary.Ĭm to In conversion table in to cm conversion table inįeet to meters conversion table ft to m conversion table ft Sample task: convert 25 miles to kilometers.
Metric distance conversion how to#
Our converter supports many different pairs of units, so we provide examples on how to perform unit conversions for only the most popular pairs.
An imperial to metric converter can be helpful in such situations. Since both systems coexist in the modern world, unit conversion is often needed when dealing with goods purchased from parts of the world using the other system. Its base unit is the meter, initially defined by a metal bar standard, but then redefined more precisely as the distance light travels in a vacuum in 1/299,792,458 seconds. It is used in all sciences, in engineering, navigation, etc. The metric system is a relatively modern system of units and is the official system for most countries in the world. Historically the definitions of the imperial units varied with time and place, but were set relative to the standard meter by a 1959 international treaty. It is currently used only in the United States, United Kingdom, and a couple of other countries, and even there it is defined by using the meter as a de facto base unit. The Imperial system, sometimes referred to as the English system of units is an old system of measurements that was used throughout human history, with evidence of its use in ancient Greece, ancient Rome, the Middle ages, and more.
Metric distance conversion iso#
It uses the standards defines by the International System of Units and ISO standards on quantities and units, with the league being the exception, as there is no single definition for it - we are using the U.S. This online imperial to metric unit converter supports conversions from inches (in), feet (ft), yards (yd), miles (mi), nautical miles (M), and leagues (lea) to nanometers (nm), micrometers (μm), millimeters (mm), centimeters (cm), decimeters (dm), meters (m), and kilometers (km).
