A while ago there was a formula posted for finding out how much you would be pressing if you were using a barbell instead of two dumbbells. For example... Two 100 lb dumbbells is equal to how much in a barbell press.
Also, how accurate in the One Rep Max Calculator?

Joe,
Charles Poliquin suggested the following formula for conversion between dumbbells and barbell. Personally, it is not totally accurate for me, but I guess it's a decent estimate.
Dumbbell weight = 0.90((Barbell weight)/2)
Or you can dumbbell press 90% of your barbell press, half of that 90% in one hand, half in the other.
I don't think 1RM calculators are very accurate.

75 pound dumbells x 2 = 150 Pounds. (I do this for 10-12 reps)
(150)(0.90)=135
150+135= 285
285 pounds might be right for me...I havnt used a barbell in about 7 months. I dont know if that would be right or notMod at universal-muscle.com

Tony you did the formula a little wrong.
In my experience, my barbell bench press was higher than the formula predicted. The inverse of this is that my dumbbell bench press is lower than this formula predicted.
Tony two 75's is used in the formula like this.
(75*2)/0.9 = barbell bench
That means a barbell bench of about 170 for the same number of reps.

alright,
Your calculation is off because i know i can do a lot more than that. I dont think there is a formula to figure out how much you would use with a barbell.
Because this one isnt rightMod at universal-muscle.com

I agree Tony.
It wasn't my formula, it was one that Charles Poliquin suggested.
Check this out, frlom Question of Strength, Testosterone issue 24
"Of course, it's possible that your stabilizers are poor, too. If they're up to snuff, you should be able to do 90% of the barbell bench press weight when doing semi-supinated dumbbell presses. In other words, if you bench 200 pounds, you should be able to press a pair of 90 pounds (2 x 90 = 180 pounds, which is 90% of 200 pounds)."
