How I learned how many pounds in a kilogram:
My doctor had an old fashioned beam balance scale to measure a patient's weight, the type where you stand on the scale and slide weights across a calibrated beam to find the balance point. The calibrated scale had a pivot at each end, so it could be inverted. One side of the beam read in pounds, the side other read in kilograms. I think the doctor liked to record the patient weight in kilograms in his charts.
On one visit, it so happened that when I stepped on the scale, I weighed 220-lbs. The nurse flipped over the calibrated beam to reveal the weight in kilograms--100 exactly. I felt a little lighter at 100-kg than I did at 220-lbs. Before that visit, I would have needed to look up the conversion. But ever since then, I've known the conversion factor in my head.
