How do I make sure my scale is working?

My food scale is acting really weird. I measured a bag of potatoes ( out of the bag, of course,) that was meant to be 680g and it scaled to 655. So to check the scale, I measured 227g pack of mushroom and it came out as 226g (and there were probably some crumbs left behind in the package so that's pretty accurate.) so how can I figure out if my scale is working? Or if it's just improperly packaged potatoes? I don't have any other full packages with labeled grams on the pack to check with

Packages can be up to 20% off. Measure water. 1 liter = 1000 grams.

This. The metric system is a beautiful thing for calibration.

It's all relative. You are looking at downward trends and scale weight is really not that important in the scheme of things.

She's talking about a food scale..

OP, you can take the suggestions above. Honestly the potatoes were probably just off. It's happened to me before as well.

Okay thanks guys! The scale is fine. It was just a bad bag of potatoes lol!

I work in a lab. If I had a calibrated graduated cylinder at home I would test the scale with water. I don't think I would use my kitchen measuring cup to test a scale.

I would probably use quarters. 1 quarter is 5.670 grams. 15 quarters should be 85 grams.
