270 kg for 12 reps
Estimated one-rep max: about 366 kg (807 lb). The five formulas span 346–389 kg, so treat it as a range rather than a number.

So is 366 kg a good bench press?
If that lift is a bench press, 366 kg (807 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

270 kg × 12 — common questions
What is my one-rep max if I lift 270 kg for 12 reps?
About 366 kg (807 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 346 to 389 kg, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.
Is 366 kg a good bench press?
If the lift is a bench press, 366 kg (807 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 146 kg × 5, 201 kg × 5, 256 kg × 3, 293 kg × 2, 329 kg × 1, then the working single at 366 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
