Calibrated scales.

[For want of a better word]

In honeyshows there is often one or two jars showing daylight between honey and lid. They are known as "yorkshire pounds" by the judges.

Never heard that one....... down here we have Cornish miles, sign post will give Truro 2 3/4 miles... then the next one closer as the crow flies... Truro 4 1/2 miles!!!

Yup...we give it away. It's why my labels state "Minimum Weight"...And my comb honey labels say weigh between 6-9oz (with the grams added as well).

Good KISS solution
