Unit converter size

A unit of measurement is a defined magnitude of a quantity that it used as a standard for measurement for the same kind of quantity, such as measurements of length, weight, and volume. In the past, many systems of measurement were defined on a local level, and could be based on factors as arbitrary as the length of a king's thumb.

While this may work on a local level, when considering trade, as well as science, having systems of units based on units that others may not be able to relate to or understand makes interaction difficult. As such, the development of more universal and consistent systems developed over time. Today, some of the systems of units in use include the metric system, the imperial system, and the United States customary units.

The International System of Units SI is the standard metric system that is currently used, and consists of seven SI base units of length, mass, time, temperature, electric current, luminous intensity, and amount of substance. Although SI is used almost universally in science including in the US , some countries such as the United States still use their own system of units.

This is partly due to the substantial financial and cultural costs involved in changing a measurement system compared to the potential benefit of using a standardized system.

As such, many unit converters including this Conversion Calculator exist, and will continue to do so to ensure that people globally are able to communicate different measurements effectively. The Arabs used coins as a measurement of units of weight since a minted coin could not easily be cut or shaved to reduce its weight, and thus provided a measurable standard.

They used a coin called a silver dirhem as a basic measure of weight, which had a weight roughly equivalent to 45 fully grown grains of barley. Note : In the formula, you must use the right shortening of measurements.

For example, you can use the "yd" but not the "yard", "lbm" but not the "Pound mass", etc. For most starter users of Microsoft Excel, it's hard to remember the exact shortening of all measurements, and might have problems to apply the Convert function.

Kutools for Excel 's Unit Conversion tools is able to convert between various unit measurements quickly. Kutools for Excel includes more than handy Excel tools.

There have been a number of different standards for the inch in the past, with the current definition being based on the international yard. One of the earliest definitions of the inch was based on barleycorns, where an inch was equal to the length of three grains of dry, round barley placed end-to-end.

Another version of the inch is also believed to have been derived from the width of a human thumb, where the length was obtained from averaging the width of three thumbs: a small, a medium, and a large one. It is also sometimes used in Japan as well as other countries in relation to electronic parts, like the size of display screens.
