The hardest part is remembering that a kg is about twice as heavy as a lb so kgs are about half. This is accurate give or take about 10%.
2.2 lbs per kg. Multiply by 2 and add 10%.
eg. 5 kg x 2 = 10 + 10% (1) = ~11 lbs.
0.45 kgs per lb. Divide by 2 and subtract 10%.
eg. 11 lbs / 2 = 5.5 - 10% (0.55) = ~5 kg.
