Divide the kilogram value by 0.45359237, the exact mass of one pound in kilograms. So 148 kg ÷ 0.45359237 ≈ 326.28 pounds.

Multiply by 0.45359237: 326.28 lb × 0.45359237 ≈ 148 kg. The factor itself is exact by definition — the tiny gap on the way back comes only from rounding the printed pound value.
