    I was given this problem...
    Given: "daily intake of 0.8 grams per kg of body weight"
    Calculate ounces of protein per day using .8 gram per kg of body weight for a 150 pound person.
    Then convert to ounces per day.

    I used the process below...

    Step 1: Convert weight in pounds to kg
    150 = weight in pounds
    2.2 = kg/pound conversion factor
    68.18 = weight in kg

    Step 2: Calculate daily budget
    68.18 = weight in kg
    0.8 g/kg = daily budget factor
    54.55 = daily budget in grams

    Step 3: convert to ounces per day
    40.91 = grams per day allowed
    0.035 g/oz = conversion factor
    1.91 oz/day = ounces per day

    But this is wrong according to the published answer of approximately 4 to 6 ounces per day...
    as published HERE in paragraphs 3 and 4.

    Where am I going wrong with the above calculation?

    Thanks for any help.

    Your first statement is wrong. There are NOT "2.2 kg/pound", there are 2.2 POUNDS PER KG. So there are 1/2.2= 0,45 kg/pound.
