To convert parts per million (ppm) of a substance to grains per gallon (gpg), you need to know the atomic or molecular weight of the substance. Once you have this information, you can use the formula: gpg = ppm x (atomic/molecular weight/7000). How do you convert 2 percent to ppm...
factors that will reduce the softening capacity of a softener. These items cannot be picked up in a standard hardness test. To arrive at compensated hardness, multiply the figure on the right by the hardness in grains per gallon by your test that fit into the hardness category on the left....
However, it is critical to never store the probe in distilled or deionized water, as this can damage the electrode by causing essential ions to leach out of the internal reference solution. In addition to proper storage, it is advisable to clean the pH probe after every use to remove any ...
After observing backpackers struggle for years with compass orientation, I am absolutely astonished that dogs can not only calculate declination, but can actually detect small changes in it. Let’s see, for 17 degrees westing, do I subtract or add that to the heading? It’s gotta be add, r...
To do this, we need to calculate the optimum mash ratio that will give us that volume, including the water that will be absorbed by the grain. Then the batch sparge brewing process becomes as easy as conducting the mash, draining the first runnings to the boiling kettle, adding an equal ...

For some sensory bins, I have made graded shades of colored pasta for a fun twist. This has also allowed me to experiment with how much food coloring per cup of pasta to achieve the desired shades! Store your dyed pasta in gallon zip lock bags when finished, and reuse often!
Here’s how to calculate the amount of oxygen absorbers you should add:↓ Selecting the Proper Oxygen Absorber Size For StorageIf done right, your rice will no longer be exposed to any oxygen.And since mold cannot grow without it, your rice becomes safe from spoilage.Also, if you want to...
You can use the "12 calories per pound" rule, or you can get more precise by looking at the formulas in How Calories Work. Pick your "ideal weight" -- the weight that you would like to maintain. Then calculate how many calories a day you can consume to maintain that weight. The...
