[14] [15] Otherwise, water hardness is measured in the dimensionless unit of parts per million (ppm), numerically equivalent to concentration measured in milligrams per litre. [14] [15] One grain per U.S. gallon is approximately 17.1 ppm. [14] [note 1] Soft water contains 1–4 gpg of calcium carbonate equivalents, while hard water contains 11 ...
World trade of rye is low compared with other grains such as wheat. The total export of rye for 2016 was $186 million [32] compared with $30.1 billion for wheat. [33] Poland consumes the most rye per person at 32.4 kg (71 lb) per capita (2009), followed by the Nordic and Baltic countries. The EU in general is around 5.6 kg (12 lb) per capita.
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials . This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
The modern American or US bushel is rounded to exactly 2150.42 cubic inches, a difference of less than one part per ten million. [ 5 ] In English use, a bushel was a round willow basket with fixed dimensions, and its inside measurements were as follows - base diameter 12 inches, top diameter 18 inches, height 12 inches - thus giving a volume of ...
One sheng equals 10 ge or 1/10 dou, though its specific capacity has varied by times and regions. Nowadays, 1 sheng is 1 liter in China, [2] [3] 1.8039 liters in Japan [4] and 1.8 liters in Korea. [5] Sheng is a traditional measure for cereal grains. Now, like "liter", sheng is more often used to measure liquid or gas. [6] [7]
Particle size distribution can greatly affect the efficiency of any collection device. Settling chambers will normally only collect very large particles, those that can be separated using sieve trays. Centrifugal collectors will normally collect particles down to about 20 μm. Higher efficiency models can collect particles down to 10 μm.
In the metric system, there are only a small number of basic measures of relevance to cooking: the gram (g) for weight, the liter (L) for volume, the meter (m) for length, and degrees Celsius (°C) for temperature; multiples and sub-multiples are indicated by prefixes, two commonly used metric cooking prefixes are milli-(m-) and kilo-(k-).

In the early 14th century several other specialized weight systems were used, including the weight system of the Hanseatic League with a 16-ounce pound of 7200 grains and an 8-ounce mark. [citation needed] However, the main weight system, used for coinage and for everyday use, was based on the 12-ounce tower pound of 5400 grains.
