Definitions for "Grains"
Keywords:  oats, cereal, corn, wheat, rye
Refers to the commodity futures markets for corn, oats, and wheat. A broader definition would include soybeans.
the seed or fruit of cereal crops
Grains are the seeds or fruits of various food plants including cereal grasses. The examples of wheat, corn, oats, barley, rye and rice provide a partial list. Grain foods include foods such as bread, cereals, rice and pasta.
The Imperial System for measuring the weight of bullets. A grain is equivalent to approximately 63.8mg.
This is the standard measurement for the weight of an arrow, broadhead or fieldpoint.
A unit of measure commonly used in water analysis for the measurement of impurities in water (17.1 grains = 1 part per million - ppm).
Exposed and developed silver halides which have formed black metallic silver grains, producing the visible photographic image.
Discrete particles larger than 0.074 mm. They may form the rock framework, similar to sand grains in a sandstone, or they may be subordinate to smaller particles in the rock.
Exposed and developed silver halides which form black metallic silver grains which produce the photographic image. Generally speaking the higher the film speed (ASA - ISO) the greater the grain effect. So a 1600 ASA will produce excessive grainy looking images, whilst a 50 ASA will produce fine grain and much better photos. Fast film is used mainly for low light photography; e.g. Astrophotography and dark interiors where flash is not allowed. The film's emulsion's sensitivity to light also influences physical properties, such as grain size. In other words a direct relationship exists between the sensitivity of the film and the apparent size of the silver grains which make up the final image quality. Films which are high sensitivity to light are characterized by larger silver grain particles, whilst The lower sensitivity films produce much smaller grain particles.

Grains are the individual crystals of the material.
In metallurgy, a cluster of crystals with a common orientation. Grain size is important to knifemakers because grain size affects the strength of a metal. A large-grain structure, because it has fewer grain boundaries, is not as strong as small-grained material.
Crystals in metals and alloys.
