Honey weighs half again as much as an equal volume of water, according to Convert-To.com. For example, 1 pint of water weighs 16 ounces, but 1 pint of honey weighs 24 ounces.
This is an average metric, but the true weight of honey by volume may vary depending on how much water is present in the honey being used. Bee Craft notes that honey that contains more than 20 percent water by volume is at risk of fermentation. Honey kept in improperly sealed jars may absorb water from the atmosphere, lowering the honey's density slightly and leaving it at risk for fermentation. To prevent this, it is important to store honey in tightly sealed containers in a cool, dry place.
