Tips for product listings

Marketplaces often ask for dimensions in inches and weight in pounds for US listings, but centimetres and kilograms for EU or Asian ones. Convert once, then round sensibly: keep two decimals for weight, one decimal for dimensions.

Need the volumetric weight too? Use the volumetric weight calculator.
