what is "8 ounces" of canned pineapple?

hi - i want to make a carrot cake recipe from Bobs Red Mill website (the mill in Portland OR - the products are well-known in the Pac NW incl Vanc Canada) - and it asks for "8 ounces" of tinned (canned) pineapple - which size can is that? I am in Canada so we are used to metric and tins of food are measured in ml's

i have pasted the cake recipe below - and here is the link

BTW - this is a great carrot cake recipe and it uses the Bobs Red Mill "whole wheat PASTRY flour"

i usually double it to make a 9" diam round layer cake.

•1/2 cup Brown Sugar
•1/2 cup White Sugar
•1/2 cup Canola Oil
•2 Eggs
•1/2 tsp Salt
•1 tsp Cinnamon
•1 cup Whole Wheat Pastry Flour
•1 cup Carrot, grated
•3/4 tsp Baking Soda
•1 tsp Baking Powder
•1/4 cup Walnuts- Baker's Pieces
•8 oz Pineapple, crushed and drained

  1. 224 ml

    EDIT Fatfingered my calculator

    1 oz = 28 grams

    1 gram = 1 ml (for water at sea level anyway)

      If you type any measurement into a Google search window it will give you the conversion ie: "8 oz. in Grams"

      1. further question - and this applies to more than just this recipe - does the recipe mean LIQUID ounces or WEIGHT ounces (for example, i know there are 8 ounces in a cup (a baking measure cup) --- and as it turns out, there are approx 32 ounces in a liter (pyrex up here has metric and imperial)

          They are very close to the same when we are talking about your pineapple since its mostly water. If you were talking about flour or something it would be a huge difference.

          1 ML of water = 1 gram at sea level and all that nonsense.

        2. There is a difference between US & UK fluid ounces (albeit slight).

          That said, 8 US oz = 237ml

          Dole Cda sells its crushed pineapple in 398ml cans (14UK oz)


          Once you've drained it and measured out your 237ml amt, you will likely not have much leftover in any event, at least that's been my experience.

            This Dole 8 oz can is probably what the recipe author has in mind, which is marked as 227g. When using a canned product, usually recipes specify the canned weight, not the drained weight.

            In this recipe I doubt if the quantity of pineapple is critical, since it is drained and thus does not contribute much to the liquid balance of the batter.

          2. Isn't a cup the same as 8oz for all intents.... + or - an ounce.

            I do not bake....

                no it's not. 1 cup of chopped nuts will not necessarily weigh 8 oz.

              2. it's the short, squat can of crushed pineapple. Can size approximates 5 mm tall and 8mm in diameter.

                    Yes, thanks! I was looking at a 12-inch ruler, and the opposite side was labeled mm, but of course that was to indicate the increments of the larger cm measure. Thank you for the clarification.

                1. I, too, am trying to figure out how much pineapple to use in a recipe I want to try. My recipe calls for 1 can (5 1/2 oz) crushed pineapple with juice. I picked up a small can today 398 ml. I sounds like the same size as yours (8 cm x 8 cm). So do I weigh the contents of the can and then measure out 5 1/2 oz?

                  I am so grateful to the government that only metric is allowed on cans. There is both in the US - at least on the items I have purchased there. I think the metric system is firmly entrenched in Canada now so why not loosen up? Shades of the Quebec mentality.

                    When I use a recipe that calls for 8oz, I use the can that says 8oz. I don't open it, drain it, and remeasure. Use the conversion as to your measurement, of course.
                    I find that these recipes want you to use the can of pineapple, I drain the cut (not the crushed), but I don't remeasure.

                    1. re: subrosa39

                      Pineapple is mostly water, so the water equivalence 1cup = 8oz is fine. So I'd use something between a half and full cup of the pineapple.

                      I doubt if the exact quantity matters. When a recipe calls for a whole can they are just using the size the roughly fits.

                      How old, or new, is this recipe? I don't see 5 1/2oz on the US Amazon.

                      But assuming those are USA oz, a little math gives:

                      5.25 oz * (227ml/8oz) = 149 ml

                      149ml / 399ml = 4/10 of your can

                        This is a recipe from a recent book, "The Coconut Miracle". I couldn't find a 5 1/2 oz can of crushed pineapple and wondered if it was a typo and it should read 15 1/2 oz can. I did the conversions (5 1/2 oz, 156 ml or .66 cups). It doesn't feel right somehow but I guess loaf cakes are fairly forgiving. This recipe is for Coconut Banana Bread and calls for 1 cup of coconut oil. I hate to waste it.

                        1. re: subrosa39

                          Is this it

                          With 4 c of flour, and no other wet stuff except the coconut oil, and 1 banana, 15 oz of pineapple and juice makes more sense than 5 oz. I bet that if you made it with 5 oz, the batter would be stiffer than biscuit dough.

                          1. re: paulj

                            Thank you paulj for going to the trouble of looking up this recipe. Yes, it is the one I'm planning on using. I could use a familiar recipe and substitute coconut oil but I thought it would be better to use one specifically formulated for coconut oil. It is solid (semi) at room temperature so that may affect the texture of the batter somewhat. You're right about the amount of liquid being low.
                            Coconut oil is now available at Costco so the price is less prohibitive (but still pricey).

                            1. re: paulj

                              The recipe does not inspire confidence. It says to *pour* batter into two greased and floured 9"x5" pans and then at the end it says, "Makes 1 loaf".
