How much does an egg weigh or a cup of rolled oats or a cup of honey for that matter?

On this blog, there has been a lot of interest in the weight of a cup of flour. So I thought I would follow that post up with the weights of various other baking ingredients. The original post can be found here.
Remember that weighing your ingredients on a digital scale increases accuracy and makes you a better baker. The digital scale I recommend in here.  Precision in baking is key.
The following table was built based on research I did on the Internet and in my cookbook collection.  And, a funny thing happened on the way to the digital scale.  No one seems to agree on what ingredients weigh!  Amazing.  How long have we been baking around the world?
What I decided to do is show you the results of my research while at the same time listing what I use in my kitchen.  You will have to make up your own mind as to what a cup of corn syrup weighs or any other ingredient for that matter.
I hope this helps in your quest to be a better baker.

    Don’t forget that a cup means different things around the world. In the US it’s 8 fluid ounces or about 240ml. In the metric system, it’s 250ml.

      @Caitlin Not exactly. If you have a Pyrex measuring “cup” then the top mark in ounces is 8 or 1 cup while the top mark on the metric side is 250 ml. But the two marks are not the same height. These are fluid measurements. I assume that Bill is using a dry measuring cup and I really have no clue how many liquid ounces are in it.

    Thank you SO much for these. I always use my scale and homespun recipes are never done in weights. Oh, a packet of yeast is 1/4 oz. I like to use a single bowl on the scale and toss in all my dry ingredients so no need for measuring utensils, just watch the numbers.
