Free Honey Weight to Volume calculator with clear step-by-step results.
Honey is about 1.42 g/ml, far denser than water, and that density depends on moisture content - the single most important honey quality parameter. Temperature has a smaller but measurable effect, so both are used to derive the density before converting weight to volume.
Density from moisture
Density = 1.4457 - 0.0128 x (moisture % - 13), at 20 C
Volume
Millilitres = grams / density
Water is far less dense than the sugars it displaces, so honey at 21% moisture is noticeably lighter per millilitre than honey at 15%. Above about 20% moisture, honey also risks fermenting.
Roughly - around 21 g at typical moisture. Because honey clings to the spoon, weighing is much more accurate than measuring by volume.
