South African units of measurement

A number of units of measurement were used in South Africa to measure quantities like length, mass, capacity, etc. The Imperial system of measurements was finally made standard in 1922. The metric system was adopted in 1970 in South Africa.[1]

System before metric system

British and old Dutch systems were used.[2]

Length

The Rhynland rood (Rijnlandse roede) was a standard Dutch measurement. It was changed in 1859 to the "Cape Foot" due to a drift in standards.

1 Rhynland foot (Rijnlandse voet) = 12 Rhynland inches (Rijnlandse duim) = 1.030 English feet.
1 Rhynland rood = 12 Rhynland feet = 12.36 (≈12.4) English feet.
1 Cape foot = 1.033 English feet.
1 Cape rood = 12 Cape feet = 12.394 (≈12.4) English feet.

Cloth Measure

1 elle = 27 Rhynland inches[3] = 2.25 Rhynland feet [0.685 m][4].
1 English yard = 34.85 (≈35) Rhynland inches[5] = 2.916 Rhynland feet

Mass

32 loot = 16 Dutch ounces = 1 Dutch pound.
1 Dutch pound = 1.089? (≈1.1) English pounds
1 English pound = 0.918 (≈0.92) Dutch pound.

One bundle was equal to 0.699 (≈0.7) lbs. [0.3175 kg].[6].

Area

One morgen was equal to 85000 m2.[7].

Capacity

Several units were used. Some units are provided below:

Dry Measures

These were used to measure rice and salt.

1 gantang [9.2 l, 2.02 Imp. gal.]: Derived from a Malaysian dry measure used on Java, Borneo, and the Moluccas and Celebes Islands.[8]
1 balli = 5 gantang [46 l, 11 Imp. gal.]: Derived from an Indonesian dry measure used on Sumatra[9].

Corn Measures

These was used to measure grain.

1 schepel [27.275 l, 5.999 (≈6) Imp. gal., 0.749 (≈0.75) Imp. bushels.[10][11]] Derived from an old Dutch word for a measuring spade or scoop used to portion out seeds or grain[12]. It fell out of favor by the end of the 19th century.
1 muid (sack) = 4 schepels [109.1 l, 23.998 (≈24) Imp. gal., 2.99 (≈3) Imp. bushels][13] Derived from a medieval French word for a dry measure of seeds large enough to plant a set area of land.
1 quarter [290.95 (≈291) l, 64 Imp. gal., 8 Imp. bushels] ≈ 11 schepels [300.025 l, 65.99 (≈66) Imperial gal., 8.249 (≈8.25) Imp. bushels][14]: A standard measurement of grain equal to a quarter of a short ton [500 English lbs., 227 kg] in weight.
1 load = 10 muids = 40 schepels [1091 l, 29.98 (≈30) Imp. bushels][15]

Liquid Measures

The country didn't have a unified system of liquid measurement because the Afrikaners used the Dutch gallon and the British used the Imperial gallon. However when measuring alcohol, there was an anomaly in which the British system was used only for ale and beer and the Dutch system was used only for wine, brandy and distilled spirits.

The firkin, kilderkin, barrel, hogshead, and butt were traditional British measurements of capacity for standard ale and beer containers based on the British ale gallon. (Once there were different measures for ale and beer before the Ale gallon measure became standard for both in 1688; the Ale gallon then became the Imperial gallon in 1824).

1 firkin [9 Imp. gal.]: "Fourth"; a measure that was a fourth of a barrel. A small cask similar to the anker.
1 kilderkin = 2 firkins [18 Imp. gal.]: A Dutch word meaning "little quintal".
1 barrel = 4 firkins = 2 kilderkins [36 Imp. gal.]
1 hogshead = 6 firkins = 3 kilderkins [54 Imp. gal.]:
1 butt = 12 firkins = 6 kilderkins = 3 barrels = 2 hogsheads [108 Imp. gal.]

Beer bottles in South Africa were different than in other countries.

Dumpie [340 ml, 11.98 (≈12) Imp. fl. oz.]: A short-necked recyclable beer-bottle with a rounded body; the word is a nickname for a person who is short and fat. It used to be 12 Imperial ounces [341 ml], like the Canadian "stumpy" beer bottles. It was rounded down to 340 ml when South Africa converted to the metric system in 1970. Its 340ml capacity also became the standard volume for beer and soda cans until 2007, when the bottling plants converted to the 330 ml European standard. It has since been replaced by long-necked beer bottles.
"Quart" [750 ml, 0.659 Imp. fl. qt.]: The standard wine bottle was used for beer until 2008. Under the South African Breweries (SAB) Project Calabash initiative[16] in 2008 a new 750ml bottle that was longer lasting and easier to recycle was introduced. It has a cylindrical body with a necked-down conical neck, resembling a scaled-up Pilsner beer pint bottle.

The kanne, anker, ahm, and legger are obsolete 17th century Dutch measurements of capacity based on the Dutch gallon that were used for standard containers of wine and spirits. They were typically sold in ankers, half-aums, and leggers[17] until 1922, when the Imperial measurement system went into effect. The "Dutch gallon" used was based on that of Amsterdam[18] .

1 kanne (can) = 1/388 legger [11/32 (≈0.34375) Dutch gallons, 1.329 l, 1.17 Imp. qts.] A Dutch and German term for a measure of alcohol that was enough to fill either 2 steins or tankards or half a standard wine flagon or beer pitcher.
1 flask = [19/32 (≈0.59375) Dutch gallons, 2.248 l, 1.978 (≈2) Imp. qts.] A term for a measure of alcohol that was enough to fill a large wine bottle.
1 half-anker = 12.125 (≈12) kannen, 1/8 ahm = 1/32 legger [4.75 Dutch gallons, 16.125 l, 3.958 (≈4) Imp. gals.]
1 anker = 24.25 (≈24) kannen, 1/4 ahm = 1/16 legger [9.5 Dutch gallons, 32.25 l, 7.9143 (≈8) Imp. gals.] A Dutch term for a small wine or brandy cask.
1 half-aum = 48.5 (≈48) kannen, 2 anker = 1/8 legger [19 Dutch gallons, 64.5 l, 15.8286 (≈16) Imp. gals.] A measure roughly equivalent to a British rundlet.
1 ahm (aum) = 97 kannen = 4 anker = 1/4 legger.[2] [38 Dutch gallons, 129 l, 31.6572 (≈32) Imp. gals.] An ahm (anglicised as "aum" - using the French spelling) was a Dutch and German measure of beer or wine that was a portion of a legger. It was also roughly equivalent to a standard English wine barrel (31.5 Imp. gals.).
1 half-pipe [55 Dutch gallons, 208.29 l, 45.81 (≈46) Imp. gals.]
1 pipe [110 Dutch gallons, 416.58 l, 91.63 (≈92) Imp. gals.]: A wine cask.
1 half-leaguer = 194 kannen = 8 anker = 2 ahm [76 Dutch gallons, 287.849 (≈288) l, 63.318 (≈64) Imp. gals.] A measure roughly equivalent to a British hogshead.
1 legger (leaguer) = 388 kannen = 16 anker = 4 ahm [152 Dutch gallons, 575.67 (≈576) l, 126.63 (≈127) Imp. gals.] A legger (anglicised as "leaguer") was a Dutch term for a large barrel of wine, roughly equivalent to a British butt.

Gasoline

Gasoline was formerly sold in Imperial gallons [1 Imp. gal. = 4.55 l], but was switched to litres after the adoption of the metric system.
