32.64 | The Megalithic yard, as rated in Thom and North. This yard is divided into 40 inches, and a rod of 2.5 yards is also described. North adds also a HMY of 0.01 MY. |
32.727 272 727 3 | The Megalithic yard, as rated in Michel. The Megalithic Mile, rated as 5280 MY is by this approximation, 14400 feet. |
33.000 000 000 0 | This is the Spanish vara, as used in the USA, via Mexico. This yard turns up in India, as Akbar's yard, where it is divided into 25 lesser measures ('inches'). § |
36.000 000 000 0 | The imperial yard is 36 inches. |
39.370 000 000 0 | US This rates 1 metre as 39.37 inches. Legal definition in the US 1866 and 1959 |
39.370 078 740 2 | UI This rates the inch as 0.254 metres. The current international definition |
39.370 113 184 7 | UB Benoit found 1 yard to be 0.914 399 2 m |
39.370 147 198 7 | UK In 1922, Seers, Jolly and Johnson found the yard to be 0.914 398 41 metres. |
39.370 232 589 4 | UL That the light second = 299 792 458 metres, = 983 574 900 feet, UL measure. |
39.370 270 000 0 | In 1882, Rogers found the metre to be 39.370 27 inches. |
39.370 431 960 0 | UC In 1866, Clarke found the metre to be 1.093 623 11 yards. UK factor 1878 |
39.370 790 000 0 | UV In 1816, Kater found this ratio. The V stands for Victoria. Legal in 1864. |
The measures of Paris were held in great estime in the premetric Europe. A number of foreign feet appear to be defined in terms of it. The principle multiples occur at 12 (inch), 144 (foot), and 864 (toise).

131 | The Roman foot, as 1/4 Aune. This was remeasured in 1746 as 131.208333. |
139.13 | The Rhennish foot appears to be defined in terms of the Paris line. This is confirmed in the way that MS uses it. |
144 | Foot. |
147.765 333 333 | The foot of the System Usuel, being 1/3 of the metre of 443.296 lines. |
439.15 | In 1734-5, La Condamine, Godin and Bouguer measured the seconds pendulum at the equator, in Peru. The toise used in this equation becomes known as the Toise de Perou. |
440.443 185 293 | The seconds pendulum, rated on Newton's value of Paris gravity (4347 lines / s / s). |
440.559 7 | The seconds pendulum, at Paris, as measured by Lacille and Cassini. (1739). |
443.283 788 845 | In 1897, Benoit found the toise of perou (72 in) to be 1.949 090 metres |
443.295 936 000 | In 1789, Mechain and Delambre found the metre to be 0.513 074 toise. |
443.295 956 746 | The [ICT] gives the toise as legally equal to 1.949 036 5 m |
443.295 979 490 | The value of the Paris foot in [MS] is 0.324 839 4 metres |
443.296 000 000 | PR This is the legal ratio of the metre: 1 metre = 443.296 lines Paris measure |
443.327 288 868 | Newton rated Paris's gravity (9.80665 m/s/s) as 30 ft 2 in 3 5/9 ln |
443.387 9 | The metre, based on the second's pendulum of Lacille and Cassini. |
443.440 000 000 | PA The survey of Lacille and Cassini served as an interim value. |
443.441 952 | Lacille and Cassini measured the meridian degree at 45° as 57027 toise. This is the proportional metre in lines. |
524.000 000 000 | Until 1746, the Aune was held to be 3ft 7 in 8 ln, Paris Measure. |
524.833 333 333 | In 1746, the Aune (reputedly 48 in, Roman), rated as 3 ft 7 in 8 ln 10 pt, PR. |
528 | A common rating is to set 6 Aune to 22 paris feet. This makes the Aune 3ft 8 in. |
