are

The are (symbol a) is a unit of area, equal to 100 square metres (10 m × 10 m), used for measuring land area. It was defined by older forms of the metric system, but is now outside of the modern International System (SI).

yard

A yard (abbreviation: yd) is a unit of length in the imperial and United States customary systems of measurement. Historically a yard was also used in other systems of units. The yard is equal to 3 feet or 36 inches. Under an agreement in 1959 between Australia, Canada, New Zealand, South Africa, the United Kingdom and the United States, the yard (known as the "international yard" in the United States) was legally defined to be exactly 0.9144 metres. Prior to that date, the legal definition of the yard when expressed in terms of metric units varied slightly from country to country.

kilometrage

kilometrage

1. the total distance, in kilometres, travelled
2. the number of kilometres travelled by a vehicle on a certain volume of fuel
3. an allowance for travel expenses at a specified rate per kilometre

Metrication

Metrication refers to the introduction and use of the SI metric system, the international standard for physical measurements. This has involved a long process of independent and systematic conversions of countries from various local systems of weights and measures. Metrication began in France in the 1790s and spread widely during the following two centuries. The process is sometimes called metrification.

bar

In musical notation, a bar (or measure) is a segment of time defined by a given number of beats of a given duration. Typically, a piece consists of several bars of the same length, and in modern musical notation the number of beats in each bar is specified at the beginning of the score by the top number of a time signature (such as 3/4).

The word bar is British English, while the word measure is American English, although musicians generally understand both usages. In American English, although the words bar and measure are often used interchangeably the correct use of the word 'bar' refers only to the vertical line itself, while the word 'measure' refers to the beats contained between bars. In international usage, it is equally correct to speak of bar numbers and measure numbers, e.g. ‘bars 9–16’ or ‘mm. 9–16’. Along the same lines, it is wise to reserve the abbreviated form ‘bb. 3–4’ etc. for beats only; bars should be referred to by name in full.

The first metrically complete measure within a piece of music is called ‘bar 1’ or ‘m. 1’. When the piece begins with an upbeat (an incomplete measure at the head of a piece of music), ‘bar 1’ or ‘m. 1’ is the following measure.

mensurable

mensurable

1. measurable

femtosecond

A femtosecond is the SI unit of time equal to 10^-15 of a second. That is one quadrillionth, or one millionth of one billionth of a second. For context, a femtosecond is to a second, what a second is to about 31.7 million years.

jerib

The jerib or djerib is a traditional unit of land measurement in the Middle East and southwestern Asia. It is a unit of area used to measure land holdings (real property) in much the way that an acre or hectare are. Like most traditional units of measure, the jerib originally varied substantially from one location to another. However, in the Twentieth Century, the jerib has been regionally, if not uniformly defined. In many countries where it was traditionally used, it is equated with the hectare, for example in Turkey and Iran. In Afghanistan, however, it is standardized at 1/5 hectare (2000 square meters or 0.494 acre).

commensurable

Generally, two quantities are commensurable if both can be measured in the same units.

Metrication

Metrication refers to the introduction of the SI metric system as the international standard for physical measurements—a long-term series of independent and systematic conversions from the various separate local systems of weights and measures. Metrication began in France in the 1790s and spread widely during the following two centuries.

Talent

The talent (Latin: talentum, from Ancient Greek: τάλαντον "scale, balance") is an ancient unit of mass. It corresponded generally to the mass of water in the volume of an amphora, i.e. one foot cubed. Depending on the length of the respective, legal foot, this corresponds roughly to the mass of 27 kg or about 60 English pounds.
