Wheel Weight Conversion Chart: Grams to Ounces (5g - 500g)

Balancing machines in the US read ounces; most of the rest of the world reads grams. This wheel weight conversion chart converts both directions across the full range - passenger car strips through 500 g truck weights - so ordering in the wrong unit never costs you a container of the wrong stock.

Ordering notes

Match the machine, not the market habit - order OZ series if your customers' machines read ounces.
Mixed-series orders are normal - gram and OZ can ship in the same container; just state both lists clearly.
Truck range runs to 500 g - see the truck wheel weights guide for the 5 g - 500 g series.
Strip sizes and segment layouts are a separate topic - see the adhesive wheel weight sizes guide.

Ready to order? Browse the wheel balancing weights range or send your size list in grams or ounces - both are fine.
