Spårvidd 1485 mm eller fem fot i Sverige? (Bana)

Enligt gamla meterboken 1883 var 1430 mm 4 fot 8 tum 1,6 linier.
1440 dito dito och 5 linier. 1435 då 4 fot 8 tum 3,3 linier.
5- 1,6= 3,4 delat med 2=1,7+ 1,6 = 3,3
En linie var 2,97 mm. Men 10 linier var 21 mm. så måtten gick aldrig jämt upp.
Inte så konstigt att man allmänt sa´ 5 fot.
Gemene man kunde ju knappt räkna. Desto mindre hålla alla siffror i huvudet/ Sune.
