Flaxseed in Various Units.

I eat 66 grams of flaxseed per day. (I eat it with yogurt in two batches. For each batch, I weigh out 33 g of whole flaxseeds then grind them.) Not everyone has a scale, so I found that 100 ml of whole flaxseed weighs about 64 grams. Assuming 1 tablespoon = 15 ml, that’s 6.9 tablespoons/day whole flaxseed. If you are interested in weight/volume conversion, that’s 9.5 g of whole flaxseed = 1 tablespoon. I checked this using two different volume spoons and a scale that matches another scale.

This website says there are 15.02 g of whole flaxseed in a tablespoon. I am measuring brown flaxseeds. Perhaps their golden flaxseeds are smaller and therefore more dense. The overprecision suggests this shouldn’t be trusted.

This website says there 14.17 g of “dry” flaxseed in a tablespoon. Again with the overprecision.

According to this website, there are 7.5 g of whole flaxseed in a tablespoon.

  1. Today I weighed out a bit over 3 tablespoons of whole flax seeds, and they weighed 31 g. I don’t know what kind of flax (I got them at Whole Foods Market).

    1. Aretae, I eat my flaxseed ground. I have revised the post.

      Thanks, Tom, that agrees with my measurements. There are two main kinds of flax seed: brown and golden. Whole Foods usually has golden, in my experience.

  2. “convertalot” reports:

    Not all tablespoons are the same. The Australian tablespoon is 20 ml; the British tablespoon is 17.7 ml. In most Canadian recipes the tablespoon is 15 ml while the American tablespoon is actually 14.2 ml.

  3. Seth, one question: Why do you weigh your flax seed? I buy and eat Whole Foods organic flax seed (golden is prettier, but I think brown has more oil) every morning and the health benefits are self evident.

    But it only costs 25-30 dollars for a 25 Pound bag, and it takes Months for me to go through a bag. (I put it on top of raw organic rolled oats, and top it with orange juice, like cereal, but without the dairy products.)

    1. I weigh it because weight works better than volume for measurement purposes. For example, it is easier to produce 27 grams than 2.7 tablespoons. I want to know how much I eat each day so that I can study the effect of varying the amount and so that I can get an optimal amount.
