Hi all, was just looking on the Muntons website at a kit I brewed (and am currently enjoying a glass of) and the bitterness is listed in EBU not IBU. Is there a conversion so I can work out the IBUs? Are they just the same thing? Cheers
 
if that was true then there would only be EBU or IBU. too calculate the difference you can use the formula:

IBU = -0.0065E^2 + 1.1526E – 0.6197

the E stands for EBU.

good luck!
 
so 20 ebu = 19.8 ibu
50 ebu=40.7 ibu
100 ebu = 49.6 ibu

surely it would be closer to linear...
 
Go back in time far enough and there were at least 3 ways to measure bitterness, it has for the last 10-15 years been unified, most people call it IBU (international bitterness unit) it is generally regarded as being mg/L of iso-alpha acids / L of finished beer.
American literature often calls it a BU (bitterness Unit) (US comes with a built in reluctance acknowledge there is a rest of the world - some times the poms aren't far behind)
Some of the oldest methods involved a taste test which were very non linear as well as being fairly unreproducible (best guess method). The best of the modern methods uses HPLC, very accurate and repeatable.

yet further googling says they are the same - the more we know the more we don't know....
