Modern measurement range
Six hundred shekels
5.7–8.4 kg
12.57–18.52 lb
Using the shekel by weight estimate. Merchant, sanctuary, royal, regional, and later coin standards differed. The broad range prevents a single 11 g reference estimate from being treated as universal.

What this conversion does—and does not—show
It gives a defensible modern scale for the amount stated in the verse. Ancient standards varied by time and place, so the endpoints are deliberately approximate. A volume is not a food mass, a metal weight is not a modern cash value, and a conversion does not settle a textual, archaeological, or theological debate.
