1-cup or so,
Verified Purchase(What's this?)
This review is from: Pyrex Prepware 1-Cup Measuring Cup, Clear with Red Measurements (Kitchen)
This is a great cup, except for one little thing: the measurements are wrong! 1 cup, according to this measuring cup, is actually closer to 7/8 cup. I have compared it to older PYREX measuring cups (2 cup and 4 cup sizes), as well as to a variety of other measuring cups. The other measuring cups are all consistent, both Pyrex and non-Pyrex. But the measurements provided by this 1-cup Pyrex cup are consistently too low.
What is most astonishing to me is that none of the other reviewers has remarked about this. I hope that others will now test their own cups - it would be nice to know whether perhaps Pyrex's 1-cup measuring cups in general are okay, and I happened to end up with the lone defective unit. My measuring technique: I use the bottom of the meniscus (the curve in the surface of the liquid), which is how I was taught to do it in Chemistry and Biology laboratories. I have also compared the weights of 1 cup of room temperature water, as determined on a digital cooking scale, and found the weight of this cup's contents to be less than that of a cup as measured by other measuring cups.

Strange, but my artist and sculpture friends are sticklers for precision instruments. A cook's art is not diminished by precision either - and if Corning, the manufacturer of Pyrex, can't get their measurements right, they shouldn't be marketing measuring cups.

Cooking might be more of an art, but baking requires precision. I appreciate jeffnick's review and deem yours unhelpful.

Cooking may be moire of an art than a precise science, but
baking actually is a science and requires precision in measurements and weights to produce a predictable outcome.

omg, i swear i swear - I didn't read your post before writing mine, lol! I just saw that first post and had to write!

I am a science nerd and baker at heart, so precision is very important to me :). 1/8 cup is equivalent to 2 whole tablespoons!

Craig, I work in a research laboratory and scientific instruments, including beakers, cylinders, flasks, and pipets are very expensive. That is why researchers need to write grant proposals, because without vast amounts of money for research, a researcher could not afford even the basic instruments that you mentioned. Nice try at arrogance, though.

Thanks for your comments. I agree, of course, that "baking and cooking do not generally require such precision measurements." However, since you appear to be shopping for a measuring cup (otherwise, what would have brought you to this page?), you obviously believe that some level of precision is needed in the kitchen. So my questions: if not laboratory precision, then what level of precision is needed in the kitchen? If you're content with an error of 12.5%, would you also be content with, say 25%, or even 50%? When following a recipe, or posting a new one online, is it acceptable to introduce an error of 12.5% right up front?
