A Kilogram is 2.204622622 pounds. But for practical purposes we can consider **1 kilo = 2.2 pound conversion**. So we can convert kilos to pounds by multiplying by 2 then by 1.1or by 11 then by 0.2 depending on which is easier.

Convert kilo to pounds and pounds to kilo

42 kilos is (42 x 2) x 1.1 = 84 x 1.1 = 92.4 lbs.

57 kilos is (57 x 2) x 1.1 = 114 x 1.1 = 125.4 lbs

Or (57 x 11) x .2 = 627 x .2 = 125.4 lbs

303 kilos is (303 x 11) x.2 = 3333 x .2 = 666.6 lbs.

A Pound is about 0.45359 kgs. We can use 1 pound = 0.45 kilograms which is about 99.2% accurate for ordinary computations. To multiply by 0.45 we can multiply by 0.9 then divide by 2 or vice versa.

35 lbs is (35 x 0.9) ÷ 2 = 31.5 ÷ 2 = 15.75 kgs

78 lbs is ( 78 x .09) ÷ 2 = 70.2 ÷ 2= 35.1 kgs

120 lbs is ( 120 ÷ 2) x .9 = 60 x 0.9 = 54 kgs.

540 lbs is (540 ÷ 2) x 0.9 = 270 x 0.9 = 243kg

Note that if we multiply 0.45 by 2.2 we will get 0.99.

Simple, right?
