Good post Leather.

I can prove it mathematically for you.

To go from kg's to lbs the conversion is 2.2. So 2.2lbs = 1 kg, let's say its 2.2X=Y.

If I factor 2.2 into (2.0+0.2)X=Y, I am left with 2.0X + 0.2X = Y

From here there are a couple different shortcuts:

I can multiply the kg's by 2 and by 0.2 and add them. So for 350 kg, 2(350)+0.2(350)=700+70=770

OR (and this is what you've done)

I can multiply by 2 and recognize that 0.2 is 10% of 2. So for 350kgs, multiplying by 2 is 700, to get 10% I just knock off the last digit and get 70. 700 +70 = 770 (Really you're moving the decimal place by one digit, so it becomes 70.0, not just 70. If you had 352.5kg then you would have 705+70.5=775.5).
