The toise (fathom) was defined as exactly two metres and was as before divided into 6 pieds (or "feet") or 72 pouces (inches). The pouce was divided into 12 lignes (or "lines"). The pied and pouce, at precisely 333. 3 mm and 27. 7 mm, were about 2.6% larger than the previous Parisian measures and 9% larger than their English counterparts.
0.188 mm 7.401 thou 1 ⁄ 12 of a ligne. This unit is usually called the Truchet point in English. Prior to the French Revolution the Fournier point was also in use. It was 1 ⁄ 6 of a ligne or 1 ⁄ 864 of the smaller French foot. ligne: 1 ⁄ 144: 2.256 mm 88.81 thou 1 ⁄ 12 of a pouce. This corresponds to the line, a traditional English ...

Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales.The microwave is between 1 meter to 1 millimeter.. The millimetre (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the International System of Units (SI), equal to one thousandth of a metre, which is the SI base unit of length.
A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic.Each prefix has a unique symbol that is prepended to any unit symbol.
For example, the Nikon D3 and D700 cameras' nominally full-frame sensors actually measure 36 × 23.9 mm, slightly smaller than a 36 × 24 mm frame of 35 mm film. As another example, the Pentax K200D 's sensor (made by Sony ) measures 23.5 × 15.7 mm, while the contemporaneous K20D 's sensor (made by Samsung ) measures 23.4 × 15.6 mm.
Inches of water is a non-SI unit for pressure.It is also given as inches of water gauge (iwg or in.w.g.), inches water column (inch wc, in. WC, " wc, etc. or just wc or WC), inAq, Aq, or inH 2 O.
1 toise was divided in 6 feet (French: pieds) or 72 inches (pouces) or 864 lines (lignes) in France until 1812. In 1799 the metre was defined to be exactly 443.296 lignes or 13,853 ⁄ 27,000 toise, with the intention that the metre should equal 1 ⁄ 10,000,000 of the distance from the pole to the equator. This had the effect of making the ...
