Units of measurement used in Switzerland

A number of units of measurement were used in Switzerland to measure length, mass, etc. Metric system was optional in 1868, and has been compulsory since 1877.^{[1]}^{[2]}

##
System before metric system

Units were varied and were not in fixed values. During the transition to the metric system, units were fixed.^{[1]} Before 1856, almost every canton had its own system of units.^{[3]}

###
Length

A number of units were used to measure length. One pied (1 fuss) was equal to 0.30 m, according to the fixed value defined during the transition to the metric system.^{[1]}^{[4]} Some other units and their fixed values are given below:

1 ligne = 1/144 pied

1 linie = 1/144 pied

1 pouce = 1/12 pied

1 zoll = 1/12 pied

1 aune = 2 pied (or 4 pied^{[3]})

1 elle = 2 pied

1 brache = 2 pied^{[3]}

1 toise = 6 pied

1 ruthe = 6 pied

1 perche = 16 pied (or 10 pied^{[3]})

1 lieue = 16 000 pied.^{[1]}^{[4]}
Lieue was used as a road measure.^{[3]}

###
Area

One arpent was 400 pied^{2} or 1.44 ha

###
Mass

A number of units were used to measure mass.

####
Ordinary

One livre (pfund of the Zollverein) was equal to 0.500 kg according to the fixed value defined during the transition to the metric system.^{[1]}^{[3]}^{[4]} Some other units and their fixed values are given below:

1 loth = 1/32 livre^{[1]}^{[4]}

1 once = 1/16 livre^{[1]}^{[4]}

1 quintal = 100 livre.^{[3]}

####
Medicine (apothecary or pharmacy)

One livre was equal to 0.375 kg according to the fixed value defined during the transition to the metric system.^{[1]}^{[3]}^{[4]} Some other units and their fixed values are given below:

1 grain = 1/5760 livre

1 scruple = 1/288 livre

1 drachme = 1/96 livre

1 once = 1/12 livre.^{[1]}^{[4]}

###
Capacity

Two main systems, dry and liquid, were used.

####
Dry

Several units were used to measure dry capacity. Some units are given below:

1 quarteron (divided into 1/4 and 1/16) = 10 emine = 15 L (0.4257 bushel)

1 double quarteron = 2 quarteron

1 sac = 10 quarteron.^{[3]}

Quarteron is the volume of 30 livre of pure water at 4 °C.^{[3]} Quarteron was equal to 5/9 of a cubic pied.^{[3]}

####
Liquid

Several units were used to measure dry capacity. Some units are given below:

1 setier = 25 pot

1 muid = 4 setiers

1 pot = 1.5 L (1.585 quarts).^{[3]}
Pot was the bulk of 3 livres weight of pure water at the temperature of 4 °C. Pot was equal to 1/18 pied^{3} and was subdivided into 1/2, 1/4 and 1/8.^{[3]}
