Why are they more appreciated than the antique ones? History of the meter Even though meter is now used across the whole Europe as a standard unit, Europe once used yards and inches. The meter unit was changing with time and under the reigns of kings, until it became standard and universally accepted. This relatively precise definition of an inch was made official during the reign of King Edward the second in the 14th century.
Even though there is no proof of that, barley was used as a distance unit for hundreds of years before. It is perhaps the most popular known antique unit. More precisely it is determined by the length from the tip of the finger, positioned in right angle with the hand, to the elbow. The smaller units of a cubit were foot, hand or finger. And the larger unit than a cubit was the stride. As you have probably concluded, this unit could vary considerably because of the difference sizes of people.
All these units of measurement were valid only for Europe, while other parts of the world had their own definitions of distance units. However, in , an internationally accepted unit of measurement is accepted. And so, an agreement for yard and pound is made in February the same year. An inch was officially recognized to being 25,4 millimeters.
However, the reason for the meter to be considered as accurate and be still used as a standard measure is that it uses the Earth as a reference. History of a foot Since there was little information on the Earth, in the history people set up the units of length by using the human body. Since the human body is different, the units of distance were not standard.
Nevertheless people did their best and improvised. Archeological proofs suggest that the Romans and the Greeks also used the unit foot. This assumption is based on the fact that people had shorter feet back then, which is why a booted foot was used.
The length of a foot in the English system was between mm and mm. The foot was usually subdivided into 12 digits, called unciae from where the English words inch and ounces are supposedly derived.
However in the 16th century, a more complex process of measuring the foot length was invented. To use this converter, just choose a unit to convert from, a unit to convert to, then type the value you want to convert. The result will be shown immediately. This converter accepts decimal, integer and fractional values as input, so you can input values like: 1, 4, 0.
The numerical result exactness will be according to de number o significant figures that you choose. When the result shows one or more fractions, you should consider its colors according to the table below:. These colors represent the maximum approximation error for each fraction. If the error does not fit your need, you should use the decimal value and possibly increase the number of significant figures. Please, if you find any issues in this calculator, or if you have any suggestions, please contact us.
The maximum approximation error for the fractions shown in this app are according with these colors:.
