Efficiency Question

[floydmeddler]

Hey lads... Going out of my mind here. Calculators are throwing up different results!

What is my extraction efficiency? At 19c my hydrometer read 1046 from 29.7 litres of wort.

Please help!

Thanks
Floyd

Need more information.
Is efficiency the correct word you should be using? Do a couple of searches on Efficiency.

Need more info... efficiency is output / input ... how much grain and what type did you use?

Sorry people... used 5kg of British pale malt. That's it.

kg @ 302BD/kg = 1510pts

You ended up with 46BD @ 29.7L = 1366pts

Efficiency is 1366/1510 = 90.4%

That seems very high... Hope it's true! After I boiled the HD reading read 1058 at 25 litres. Calculated that this works out at around 85%. Anyone agree/disagree?

Thanks

Oops! Forgot to mention... added 600g of honey in at the last min of boil.

beersmith shows 5kg + 0.6 honey / 25L as 80%.
