我得到奇怪的输出，如100公斤=103公斤，而磅到公斤的转换工作得非常好，

def calculate_1rm(weight_unit, squat, deadlift, bench_press, reps):
    try:
        squat, deadlift, bench_press, reps = float(squat), float(deadlift), float(bench_press), int(reps)
    except ValueError:
        return "Invalid input, please enter a number for all lifts"
    
    if weight_unit.lower() == "kg":
        squat = kg_to_lbs(squat)
        deadlift = kg_to_lbs(deadlift)
        bench_press = kg_to_lbs(bench_press)
        weight_unit = "lbs"
    if weight_unit.lower() == "lbs":
        squat = lbs_to_kg(squat)
        deadlift = lbs_to_kg(deadlift)
        bench_press = lbs_to_kg(bench_press)
        weight_unit = "kg"

在这些转换之后，我根本没有触及这些值
我试过除以/.453592（相同的结果），并尝试将变量（深蹲，硬拉，卧推）乘以2.205，但没有运气
