A millilitre of honey is a volume amount, not an automatic gram amount. Select a honey reference before converting between a liquid measure and the quantity shown on a scale.
Choose a honey relationship
King Arthur supplies a source-tablespoon relationship. Women’s Weekly Food supplies a 250 mL source-cup relationship. Keep them separate and inspect which one supports the conversion you want.
The references do not fully quantify honey variety, temperature, or crystallization. They do not establish a universal value for whipped or crystallized honey.
Keep an original weight directly
If your recipe provides honey in grams, use those grams and apply the serving factor. A cup estimate is not needed for that calculation.
If you measure your own product, record the state, method, mass, and known volume. A custom measurement belongs to that recipe context and should not become a public universal honey reference.
Separate conversion from substitution
A converted amount does not establish that honey can replace another sweetener in the recipe. Keep the recipe’s ingredient choice and instructions when changing only the batch size.
In Baker’s percentages, keep honey as a separate ingredient. Its entire mass is not identified water, so it should not be added wholesale to the hydration numerator.
