For our lbs to kg conversion, per our pediatrician I used lbs/2.2046 but noticed that two other hospitals used lbs/2.20 in their forms. I am just wondering if anyone knows why some use 2.20. When rounded off two decimal places it does make a difference i.e. 8lbs 2 oz converts to 3.69/3.70. I did the math and 2.2046 seems more accurate but just want to be sure we are not missing something.
{fn ConvertLBStoKG(lbs){
local kgs = lbs/2.2046
if kgs == 0 then
return ""
else
return str(kgs)
endif
}}

It depends how accurate you want to be. See http://www.wolframalpha.com/input/?i=pounds+to+kilograms. There is .4536 kilogram per pound. Invert that (1/.4536) and you have the conversion value you want. 2.2045855379188712522045855379189. Carry it out to however many decimal places you find significant. I'm sure most are satisfied with an accuracy in the hundredth, which is why you see 2.20.
