Eight sets of constants, one formula.
IPF GL is total × 100 ÷ (A − B·e^(−C·bodyweight)). The IPF publishes A, B and C for men and women, classic and equipped, full meet and bench only. This calculator uses the 2020 table from the IPF’s own document.
Pick the right equipment and event above. A bench-only score uses your bench, not your total.
