The term for telescopes persisted even in the 20th century, with a telescope listed in the 1909 Sears Roebuck catalog of having 25 lignes diameter aperture, or about 56 mm (5.6 cm). [5] The measurement SPI (Stitches per inch) for leather pricking irons and stitch marking wheels also commonly uses the Paris inch instead of the Imperial inch.
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. The aune ( ell ), used to measure cloth, was defined as 120 centimetres, and divided into the demi aune (half an ell, or 60 cm) and the tiers aune (third of an ell, or 40 cm).

Because of the identity property of multiplication, multiplying any quantity (physical or not) by the dimensionless 1 does not change that quantity. [5] Once this and the conversion factor for seconds per hour have been multiplied by the original fraction to cancel out the units mile and hour, 10 miles per hour converts to 4.4704 metres per second.
The units and their preliminary values were: [7] The metre, for length – defined as being one ten millionth of the distance between the North Pole and the Equator through Paris; The are (100 m 2) for area [of land] The stère (1 m 3) for volume of firewood; The litre (1 dm 3) for volumes of liquid

Track gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. In general, requirements depend on whether the conversion is from a wider gauge to a narrower gauge or vice versa, on how the rail vehicles can be modified to accommodate a track gauge conversion, and on whether the gauge conversion is manual or automated.
