# Weights, Measures and Formulas

I don't know about you but there is no way I can keep a weights, measures and formulas catalog at my mental finger tips. It's aggravating when in the middle of creating from an herbal recipe I have to stop and search for equivalents and calculations!

Hence, the reason for this post. From now on I'll have this handy-dandy resource to pull up for easy access and will avoid the frustration that often causes a creativity wilt.

Weights and Measures:

1 lb = 453 grams
1 oz = 28.3 grams
16 oz (dry) = 1 lb
1 quart = 2 pints
1 pint = 2 cups
1 cup (fluid) = 8 oz
1 tsp = 60 drops
1 Tblsp = 3 tsps
1 oz (fluid) = 2 Tblsps
1 cup = 16 Tblsps

Capsules and Powders:
15.4 grains = 1 gram
1 gram = 1000 milligrams (mg)
1 "00" capsule - about 650 mg = 10 grains (well packed)
1 "00" capsule - about 500 mg = 8 grains (well packed)
2 gelatin capsules = 1 tsp of extract
2 Tblsps extract = 1/2 cup of tea

Formulas:
Weight (gr) = volume (ml) x specific gravity
Volume (ml) = weight (gr) + specific gravity

Common Weights:
1 gallon (H20) = 3,764.88 gr
1 gallon (ETCH) 190 proof ethyl alcohol = 3,081376 gr

Liquid Equivalents:
1 oz = 29.57 ml
1 pt = 16 oz = 476.33 ml
1 qt = 2 pt = 4 cups = 32 oz = 946.6 ml
1 gallon  = 4 qrts = 8 pts = 16 cups = 128 oz = 3,784.95 ml

Solid Equivalents:
1 oz = 28.4 gr
1 lb = 16 oz = 453.6 gr
1 kg = 2.2 lbs = 35.2 oz = 1000 gr
