+1 with @Stressbaby. I had 1 TBS measure at 3.8 grams, but I think mine was exposed to some moisture due to not storing an open baggie properly. Plus I lent out my calibration weights and have yet to see them come back (and can't remember who I gave them to since it was some time ago), so I'm unsure if my scale is still calibrated properly (seems okay, but that doesn't mean much without the weights).
