The grain per gallon (gpg) is a unit of water hardness defined as 1 grain (64.8 milligrams) of calcium carbonate dissolved in 1 US gallon of water (3.785412 L). It translates into 1 part in about 58,000 parts of water or 17.1 parts per million (ppm).

['Multiply the number of people in your family times 70 (gallons of water used per day, national average).', 'Multiply the answer by your water hardness in grains per gallon (to convert mg/l or ppm to grains, divide by 17.1). ... ', 'This is your "grains per day" number.']

In both cases, you can count a serving of whole grains as 16 grams (16g) of whole grain ingredients. A small amount of whole grain translates into big health beneﬁts! 16 grams of whole wheat ﬂour, for instance, would equal about one and half tablespoons.

The milligram is a very common metric unit of mass equal to 0.001 gram or 1000 micrograms (µg or mcg). One milligram equals approximately 0.015432 grain or 35.274 x 10E-6 ounce.

Since the implementation of the international yard and pound agreement of 1 July 1959, the grain or troy grain (symbol: gr) measure has been defined in terms of units of mass in the International System of Units as precisely 64.79891 milligrams. 1 gram is approximately 15.43236 grains.

The answer is: The change of 1 tbsp ( tablespoon ) unit in a medium grain brown rice measure equals = into 11.88 g ( gram ) as in the equivalent measure and for the same medium grain brown rice type.

This means that 6.022x10^23 grains is equivalent to 1 mole of rice grain.

Now it is a simple matter to find how many atoms there are in a grain of salt. (Note that one mole contains Avogadro's number of atoms, which is 6.02x1023.) So a grain of salt contains about: 5.85x10-5 gr/ (29.25 gr / 6.02x1023) = 1.2x1018 atoms, half of which are sodium atoms.

Think of these concentration measures as being like a percentage. Just as 1 percent is one part of a hundred, 1 ppm is one part of one million. ... It takes a million milligrams to make up a kilogram; therefore, one ppm is equivalent to one mg/kg.

A serving is considered 16 grams of whole grain (ingredient) in a whole grain product. Some exact serving sizes of whole grain foods are: 1/2 cup cooked brown rice, 100% whole grain pasta, oatmeal, or other cooked grain; 1 slice 100% whole grain bread; or 1 ounce of 100% whole grain cereal.

ppm = parts per million ppt = parts per thousand. 1 ppm = 0.001 ppt. 1 ppt = 1000 ppm. A meter that reads 0 to 10,000 ppm is the equivalent of a meter that reads from 0 to 10.00 ppt. A reading of 5000 ppm is equal to a reading of 5.00 ppt.

The conversion factor would be 1 mg/l = 3 NTU = 1 ppm based on 1 mg/l = 1 ppm. Each application may have a different conversion factor due to the varying response of the turbidity instrument based on the particulars of the application and samples.

So now we know the number of atoms in a gram of sand, we've got to figure out how many grains of sand there are in a gram and multiply it by the number of atoms in that same weight. (Pssst, pay attention here) That means that there are 43 quintillion atoms in one grain of sand.

Environmental Science and Technology Briefs for Citizens as grams per 1,000 liters, which may be converted to mil- ligrams per liter (mg/L). Therefore, 1 g/m3 = 1 mg/L = 1 ppm. Likewise, one milligram per cubic meter (mg/m3) is the same concentration in water as one microgram per liter (ug/L), which is about 1 ppb.

What's a Grain? Bullets are measured in a unit of mass called grains (abbreviated “gr.”). One pound is equal to 7000 grains, and there are 437.5 grains in an ounce. Bullets can weigh anywhere between 15 grains for the lightest 17 HMR bullets all the way up to 750 grains for the heavier .
