Understanding domestic doses and their equivalents

I've had a lot of trouble with this in the past, so I thought I'd post these numbers to help you in the future when you're reading recipes and trying out your own herbal preparations. Cups and glasses are approximate.

1 teaspoon (t) = 60 drops = 5 ml = 1 dram (double this for two drams, and so on)

1 tablespoon (T) = 15 ml = 3 t = 1/2 fl oz

1 wineglass = 1.5 to 2 fl oz = 56 ml = 3 to 4 T

1 teacup = 4 to 5 fl oz = 150 ml = 8 to 10 T

1 American pint = 16 fl oz = 453 ml

1 English pint = 20 fl oz = 567 ml

1 American quart = 32 fl oz = 906 ml

1 English quart = 1.134 liter = 1134 ml

1 ounce (oz) = 28.3 grams (g)

2.2 pounds = 1000 g

1 gram = 15 grains

1 ml = 15 drops or minims

30 ml = 1 fl oz

I also use the Online Conversion website quite frequently. I hope this helps you in your future herbal endeavors! :)
