Special thanks to Murray Reid, Andrew Matheson, Cliff Van Eaton and other Apicultural Advisory Officers of New Zealand for making many of these 'rules of thumb' available!

Beekeeping Conversions and 'Ready Reckoner'

Early 'paper' versions of many of these conversions appeared in:

Beekeepers Bulletin 6(1)84:11-19

Van Eaton, C. (1996) Beekeeping ready reckoners. BeeBiz 2:16-17.

These conversion tables are a combination of straight mathematical conversions that 'can't be argued with' but many also contain some expert knowledge. That is, some involve beekeeping rules of thumb. Obviously, you may not agree with the assumptions! If you're not sure what is being assumed, put a 1 in the first box of a table and calculate it...

You can put your 'starting' number into any of the boxes, and the calculation will convert it to the other units...

Metres Kilometres Feet Yards Miles


Area    

Sample question:

"How much larger is a hectare than an acre?"

Metres2 Feet2 Yards2 Hectares Acres


Frame Wire    

Sample question:

"How many kilograms of frame wire will I need to wire 100 full depth frames with 3 wires in each?"

Kg of wire Pounds of wire Frames (3 wire) Frames (4 wire)


Frame Nails    

Sample question:

"How many frames will I be able to nail up with 1 lb of nails?"

  Kilograms Pounds Nails Frames
30 x 1.4mm nails

Frame Wiring    

Sample question:

"How long is it going to take me to wire these 500 frames?"

Brood Production And Egg-Laying Rates    

Sample question:

"If I have 5 FD frames of brood, how many eggs/day is the queen laying?"

Note: Average egg-laying rate of a young well-mated queen: 1500 eggs/day

Since the egg-laying rate of a queen decreases as she ages, this calculation shows why it is very important to requeen beehives on a regular basis.

Sugar Syrup (Metric)    

Sample question:

"I want to mix a 5 litre container of syrup - how much sugar for a heavy syrup?"

Note: 65% concentration is normally the highest sugar concentration which can be achieved by beekeepers mixing their own syrup. At concentrations above this, sugar is likely to come back out of solution, especially at lower temperatures. Fine liquid sugar (FLS) is available from sugar refineries at 67% concentration.

Note: 65% concentration is normally the highest sugar concentration which can be achieved by beekeepers mixing their own syrup. At concentrations above this, sugar is likely to come back out of solution, especially at lower temperatures. Fine liquid sugar (FLS) is available from sugar refineries at 67% concentration.

Sugar Stored (Metric)    

Sample question:

"I want to add 10kg of stores to the hive - how much do I need to feed?"

Note: To evaporate off the water and invert the sugar, bees use 0.3 kg of sugar for every litre of water in syrup.

Moisture Equilibrium    

Equilibrium between relative humidity of air and moisture content of clover honey. Below the relative humidity level, honey at this moisture content begins to lose moisture. Above the relative humidity level, honey at this moisture content begins to take up moisture.
