The conversion formula "mg = grains × 64.8" is a convenient tool for quickly and easily converting grains to milligrams. It eliminates the need for memorizing multiple conversion factors for different substances and ensures accurate measurements.
So, whenever you need to convert grains of salt (or any other substance with a grain weight of 64.8 mg) to milligrams, simply use the formula "mg = grains × 64.8" to get the desired result.
Refer to Conversion Table for Other Substances
While the conversion formula "mg = grains × 64.8" is specifically used for substances with a standardized grain weight of 64.8 milligrams, there are other substances that are also measured in grains but have different grain weights. To convert grains of these substances to milligrams, you can refer to a conversion table.
Conversion tables provide a list of substances along with their corresponding grain weights in milligrams. This allows for easy and accurate conversion of grains to milligrams for a wide range of substances. You can find conversion tables online or in reference books.
Here are some examples of substances that have their own grain weights and require the use of a conversion table:
- Wheat: 1 grain = 90 milligrams
- Barley: 1 grain = 60 milligrams
- Oats: 1 grain = 80 milligrams
- Gold: 1 grain = 64.8 milligrams (same as salt)
- Quinine: 1 grain = 64.8 milligrams (same as salt)
To use a conversion table, simply find the substance you are interested in and look up its grain weight in milligrams. Once you have the grain weight, you can then use the conversion formula "mg = grains × grain weight" to convert grains to milligrams.
For example, if you have 5 grains of wheat and you want to convert it to milligrams, you would first find the grain weight of wheat in the conversion table, which is 90 milligrams. Then, you would use the formula "mg = grains × grain weight" to calculate the milligrams: 5 grains × 90 mg/grain = 450 milligrams.
Conversion tables are a valuable resource for accurately converting grains to milligrams for a variety of substances. By referring to a conversion table, you can ensure that you are using the correct grain weight and obtaining accurate results.
