# Update Weight

> Bulk set, scale, or convert product weights for accurate shipping. Set exact values, multiply, or convert between grams, kilograms, ounces, and pounds.

Accurate weights mean accurate shipping costs. Set weights in bulk after an import, scale them to account for packaging, or convert your whole catalog between metric and imperial units.

## Update the weight
