I'm not sure if this has already been discussed and/or posted someplace else but I found this incredibly handy Online Volume Converter that can instantly convert anything from liters to ounces and tell you how many teaspoons equal how many tablespoons and on and on. You can even find out how many dekasteres equal a bushel if you really needed to know...
