JenRN30, BSN Specializes in Endoscopy/MICU/SICU. Has 10 years experience. May 16, 2009 Another quick way....for 9 lbs 6 oz6 oz out of 16 oz in a lb (6/16 = 0.375)So, add 0.375 of a lb to 9 lbs = 9.3759.375lbs /2.2 = 4.26 kgfor 17 lbs 14 oz14/16 = 0.87517.875/2.2 = 8.1362 lbs 12 oz12/16 = 0.7562.75/2.2 = 28.52 0 Likes

tfleuter, BSN, RN Specializes in ICU. Has 10 years experience. May 23, 2009 2 very different ways to get the answer, Wonder if there are other ways since 2 people still got 2 different answers for 8.13 It's all about sig figs. Where one method starts you out with a "clean" number (14/16 = 0.875) the other starts out with a repeating decimal (17/2.2 = 7.272727272727272727272.....) Depending on where one chooses to round up the number (middle of the equation or at the end) will change the outcome. In either case, both are very close, but would be a concern if you needed to be exact up to the hundredths place. 0 Likes

RossayRN May 23, 2009 thats weird because i get 17.14/2.2= 7.79=7.8 . I checked it on a converting program and the answer is still the same as mine. I have also passed all my math tests with 100% so I don't know what to say. 0 Likes

RossayRN May 25, 2009 Well until I get an instructor that tells me that 2.2lbs doesn't equal a Kilogram and all the books used that have taught me to do my math the way that I do then I'll continue to do them this way or unless all of a sudden I start failing my maths test then I am not wrong. There are many different ways to get a right answer. 0 Likes

There are many different ways to get a right answer. The problem with the way you did your calculation is that 17lbs 14oz does not equal 17.14. That is why your answer came out differently. 0 Likes

ImMrBill3, RN Specializes in ICU, Home Health Care, End of Life, LTC. Has 2 years experience. May 25, 2009 This is a fairly common mistake. 17lbs 14 ounces IS NOT 17.14lbs IT IS 17 14/16 lbs.An ounce is not a tenth of a pound but a sixteenth of a pound.An easy way to conceptualize this is hours and minutes.1 hour and 15 minutes IS NOT 1.15 hours IT IS 1 15/60 hours.Other example include inches, feet and miles; ounces (liquid), pints, quarts and gallons.Hope this helps, this is part of the reason for the change to the metric system (oh that's right we haven't changed because people are SOOO familiar with our system.) 0 Likes

kdsrn Specializes in Pediatric Heme/Onc and Pulmonary. Has 25 years experience. May 26, 2009 RossaysoonRN,I'm not sure why you are getting so defensive. I was just trying to help demarys who asked a question. You are correct that 2.2 # is equal to 1 kg. What you did incorrectly was divide 17.14 by 2.2 instead of converting your oz to pounds 1st. You would first divide 14/16 to get 0.875. Add the 0.875 to 17 to get 17.875. Then divide 17.875 by 2.2. This is a very common mistake, but in pediatrics just a little bit off can make a significant difference in the dose. 0 Likes
