Bottom line is my digital kitchen scales are close but admittedly not calibrated. SOooo ... I could see being off a couple of grams MAYBE if even. BUT not 5/8 ounce on the pound.

A nickel weighs 5 grams. A reasonable check of accuracy.

Does the weight include packaging too?

Today I bought a package of ground round that was labeled as 1.00 lbs. I weighed it on my kitchen digital scales and it came up to 438 grams vs 454 grams. In ounce mode on the digital scales it came up to 15 3/8 ounces vs 16 ounces for a pound.

So not only is the weight well under labeling but apparently the styrofoam and wrap was included. It might not seem like much but I've shopped there for 11 years and known of this discrepancy most of those years. It adds up and it isn't fair.

Are supermarket scales state regulated or is there some local entity responsible for accuracy?

My digital kitchen scale is a Salter model 3001 (measures up to 5 lbs). Not Chinese crap. Model is no longer available. I've had it a good number of years. Salter has been around doing scales since about 1760 and my scale is (VERY) accurate but not calibrated and only accurate to the nearest gram. In fact, I looked at the stickers on the back to see if accuracy data was listed and it was not. There was a "Not Legal For Trade" notice though, which I think all home scales have regardless of accuracy.

To try and answer some of the questions, yes I weighted the whole package (beef, tray and wrap) and it was 5/8th ounce under what the 1.00lb label on the ground round showed. These is no absorbent pad in packages of ground beef. I speculate that evaporation would not account for the underweight in fresh ground beef. The plastic wrap is pretty tight around the product too.

Guess I'll just have to check it out with the manager and their scales at checkout next time. I'll be sure to also select something else that isn't from the meat department, to compare weights at the cashiers scale. A loaf of bread perhaps. That too is clearly marked in ounces and grams.

If your scale is decades old and has never been calibrated, it is most likely your scale.
