Honey jar calculator
How many jars a bucket of honey fills, in each of the common UK sizes, and what is left at the end. Tell it what to keep back for the bucket and how much to fill over, and it does the rest.
13.6 kg of honey, fills
- 29 jars of 454 g (1 lb)442 g left over
- 40 jars of 340 g (12 oz)8 g left over
- 59 jars of 227 g (8 oz)215 g left over
Jarring in 454 g (1 lb)? The 442 g left at the end fills one 340 g (12 oz) jar as well.
Where these figures come from
The three sizes are the common UK honey jars, 227 g (8 oz), 340 g (12 oz) and 454 g (1 lb), and the weight on a label is the honey in the jar. Both are in our guide to selling honey, from these sources:
- Business Companion (Chartered Trading Standards Institute), Labelling of honey (last reviewed March 2026)
- GOV.UK, Weights and measures: the law
A pound is 0.45359237 kg exactly, so a 30 lb bucket holds 13.6 kg. The rest is division: we do not guess how much stays in the bucket, because it depends on the bucket and on how warm the honey is.
Before the jars go out
- Selling honey in the UK covers what the label must say, the weight included.
- Storing honey in bulk, and warming it back to jar covers getting set honey out of a bucket without cooking it.
- Soft set honey is the other way to jar a crop that wants to set.
Keep the buckets and the jars in one place
The honey store in a free Bees Knees Apiary account keeps each bucket by harvest. Jar up from one and the honey comes off the bucket, the jars go into your stock with their lot, and the sales page knows what you have.
