Quick way of doing it in your head: add 10% and then double it. It's not precise but pretty close.

Edit: sorry, it's the other way round. Lbs->kg would be dividing by 2 and substracting 10%

Check: 1lbs is 0.453592...kg

1/2 = 0.5

0.5 - 0.05 = 0.45 --> off by about 3.592g

The other way round: 1kg is 2.2046...lbs

1*2 = 2

2 + 0.2 = 2.2 --> off by about 0.0046lbs

Sorry, only read the title. Still leaving this here, might be useful for some.
