Unless https://www.math.net/pounds-to-tons https://www.math.net/pounds-to-tons is severely wrong, a US ton is 2200lbs, UK 2240lbs, metric 2204lbs. Put a different way, US to metric is a <0.2% difference (the smallest), US to UK is a <2% difference (the biggest). At a scale of 433 tons, it doesn’t really matter much which kind of tons (unless you’re actually doing the rocket science, of course).
