Old weights and measures (Bavaria)
With the ordinance of February 28, 1809, the dimensions throughout Bavaria were made binding on defined sizes. Before that, there were some regional differences. For example, the Aschaffenburg foot measured 290.50 mm and the Nuremberg foot was 303.75 millimeters. An economic reform of Montgelas should also standardize the weights and measures.
Ferdinand Malaise (1842) gives an overview of various European weights and measures for the Bavarian foot  its reference size  129.38 Parisian lines .
On April 29, 1869, Bavaria introduced the metric system by law at the turn of the year 1872 . The Bavarian foot was set at 0.291859206 meters.
The dimensional designations and dimensions, the values of which were initially set in metric units, remained in everyday use.
Length measurements
Derivation of the Bavarian foot
The Bavarian foot  like the Hanoverian foot and the Liège Lambert foot  has the exact ratio 63: 64 to the Roman foot . In practice, the Bavarian inch was created by dividing the Vienna cubit , which is 1 Roman cubits , by thirtytwo.
The old, duodecimal length measures
While the foot sizes in ancient times always in sixteen finger's breadth was divided, which continued into the Middle Ages in Europe duodecimal tariff classification by. Whereby an inch in the Romance languages is usually called "a thumb (breadth)". The duodecimal division of feet was valid in Bavaria up to and including the early modern period .
Scruples  =  0.1689 mm  (typographical, unofficial)  
line  =  12  Scruples  =  2.0268 mm  
inch  =  12  Lines  =  24.3216 mm  
foot  =  12  inch  =  291.8592 mm  Was officially set at 0.291859206 m in 1869. 
step  =  28  inch  =  0.681 0048 m  (Not mentioned in 1869.) 
Fathoms  =  6th  foot  =  1.7511552 m  
rod  =  12  foot  =  3.502 3104 m  
mile  before 1811:  =  7.414,975 km  = 25406 Bavarian feet, actually five Roman miles .  
1811/71:  =  7.470 903 km  = 25600 Bavarian feet  
from 1872:  =  7,200,000 km  (is rounded metrically)  
1896:  =  7.420 44 km 
The length of the Bavarian cubit was legally exactly 2 feet 10¼ inches, or about 83.30 cm. This rather strange ell definition can easily be explained as follows: Historically, the old Bavarian ell is undoubtedly a 45romandigitiell. Since the Bavarian foot itself measures 63/64 Roman feet, this corresponds to exactly 34 2/7 Bavarian inches. Be it out of historical ignorance or just for the sake of simplicity, it was rounded down to 34¼ inches. So you waived exactly one twentyeighth additional Bavarian customs.
The Nuremberg or Franconian yardstick, on the other hand, referred to the Bavarian foot. The Franconian yardstick measured 36 Bavarian finger widths or 27 Bavarian inches. Starting from the sevensmooth value of the Bavarian foot, one obtains the theoretical value of the Nuremberg cubit of (291.7215 ÷ 12 × 27 =) 656.373375 mm, which corresponds to about 290.968 Parisian lines and thus also with the value given in the literature empirical value of the Frankish yardstick corresponds to 291 Parisian lines.
The decimal transition length measures
After the Holy Roman Empire was dissolved in 1806 , Bavaria joined the Confederation of the Rhine and was elevated to a kingdom by Napoleon with territorial gains .
Although Bavaria did not yet dare to use the meter introduced in France since 1793, the Bavarian foot was decimalized.
This system was in place until January 1, 1872, the day the law of 1869 came into force.
Scruples  = 291.859206 µm  
line  = 10 scruples  = 2.91859206 mm 
inch  = 10 lines  = 2.91859206 cm 
foot  = 10 inches  = 2.91859206 dm 
rod  = 10 feet  = 2.91859206 m 
Area dimensions
Square inches  = 0.00059154 m²  = 5.9154 cm² 
Square feet  = 144 square inches  = 0.085182 m² 
Square mile (rare)  = about 55.2 km² (depending on the mile definition, see above)  
Bifang, Pifang  
Bed  = 9 square feet  = 0.7666 m² 
Square rod  = 100 square feet  = 8.5182 m² 
Decimals  = 4 square rods  = 34.072709 m² 
Day's work (morning, jauchert, yoke)  = 100 decimals  = 3407.2709 m² 
Hooves, hooves  = 3342 daily work 
volume
The Bavarian cubic foot is greater than or equal to 24.861044 liters. But this was not used for measure of capacity.
Measure of capacity, firm
This was used to measure all nonliquid substances, such as grain , flour , lime etc.
The unit of the lime measure was the Metzen. Lime was measured mostly in heap. The measuring body was determined to be a truncated cone . On June 7, 1811, these dimensions were determined:
 bottom diameter 1½ feet
 top diameter 1¼ feet
 Cone height 11 inches plus 8⅖ lines
 6 meats = 1 bushel
 24 Metzen = 1 courage
According to the royal Bavarian legislation of 1869: a Bavarian bushel is 1 / 0.449 725 9946 hectoliters .
Derivation
Historically, the Bavarian harlot is not derived from the Bavarian foot itself, but from the socalled Karl's foot.
This has a ratio of 9: 8 to the Roman foot and thus measures eight seventh Bavarian feet. Thus, there is between the used Bavarian cubic foot, and the actual Bavarian cubic feet, the ratio (7 × 7 × 7 =) 343: 512 (= 8 x 8 x 8). The socalled Karlsfuß measures just over a third of a meter.
Thirties (thirtysecond slashes)  = ½ sixteenths of a millet  =  1.15811l 
Sixteenth of a century , Mäßlein  = ½ eighths of a millet  =  2.31623 L. 
Eighth knot  = ½ quarter mason  =  4.63245 L. 
Viertelmetze (n), half a quarter  = ½ quarter  =  9.26490 L. 
Quarter, half slut (s)  = ½ Metzen  =  18.52980 L. 
Muck (noun)  = 34⅔ measure  =  37.05960 L. 
Scheffel ( Bavarian : Schaff, plural: Schäff )  = 6 Mets  =  222.35762 L. 
Courage  = 4 bushels  =  889.43046 L. 
Measures of measure, liquid
According to royal Bavarian legislation of 1869, the Bavarian measure is the 208th part of the volume of a Bavarian bushel at 1 / 0.449 725 9946 hectoliters .
Historically, the Bavarian measure is certainly exactly 50 Karlskubikzoll. According to this, the pecker is exactly (1728 ÷ 50 =) 34, 5 6 measure, instead of 34⅔ measure.
The resulting metrological error is exactly 1/325 = 0.308%.
Conversely, if you take the Karls cubic foot, i.e. the Metze, as the reference value, then an old Bavarian measure is not 10 69.0 27 ml, but about 10 72.3 27 ml. Thus, there was a deviation of just under 3 when serving. 3 ml.
Achterl, eighths in Francs  = ⅛ measure  =  0.133 l  
Bottle, quart (el)  = 2 figure eight  = ¼ measure  =  0.267 l 
Gazel  = ⅓ measure  =  0.357 l  
Seidel , in Franconia Seidla (half)  = 2 quarters  = ½ measure  =  0.535 l 
Measure, measure jug or mug  = 2 pints  = 3 gazels  =  1.069 L. 
Dispensing bucket  = 60 measure  =  64.142 L.  
Visireimer (beer bucket )  = 64 measure  =  68.416 L. 
Water flow rate
Steften  = 2 measures per minute  =  2.18 liters per minute 
Weights
Commercial weights
The Viennese pound was used in Bavaria . In the Middle Ages and the early modern period this was always about 561.288 g, i.e. H. two Viennese marks .
In 1811 Montgelas rounded the pound in Bavaria to 560,000 g. this should facilitate the conversion to other dimensions.
A distinction must therefore be made between an old, historical value and a reform value about a quarter percent lower :
unit  Historical value  Reform value  

Gran  =  73.084 3750  mg  =  72.916  mg  
Penny weight  =  15th  Grän  =  1096.265 6250  mg  =  1093.750  mg 
Quentchen (Quint)  =  4th  penny  =  4.385 0625  G  =  4,375  G 
Loth  =  4th  Tiny bit  =  17,540 2500  G  =  17,500  G 
Quadruplets  =  8th  Loth  =  140.322 0000  G  =  140,000  G 
lb  =  4th  Quadruplets  =  561.288 0000  G  =  560,000  G 
Note: The historical values are of course only "filled" zeros after the third righthand decimal place of the pound value in order to be able to correctly reflect the important arithmetical values of the smaller units. In any case, greater precision can either only be achieved with reference to a certain specimen of scale or via a binding definition.
Pharmacist weights
The Bavarian pharmacist weight corresponds to the Franconian, i.e. the Nuremberg pharmacist weight , as everywhere in Germany .
Historically, the Nuremberg pharmacist pound was 357.84 grams. The Kingdom of Bavaria rounded this to 360 grams under Montgelas in 1811.
Coin weights
The Cologne mark with its subdivisions was also valid in Bavaria .
