The length converter translates between metric and imperial units from millimeters to miles; inch-to-centimeter is the most common direction for screen sizes and furniture, mile-to-kilometer for driving abroad and run training. The weight converter works across grams, kilograms, ounces and pounds, handy for foreign recipes and gym plates.
For shipping and e-commerce, the dimensional weight calculator deserves special attention: it computes volumetric weight, because carriers bill whichever is higher between actual and dimensional weight. If you sell bulky products, price your shipping accordingly.
All converters run instantly in your browser. For official or commercial documents, how you round (how many decimal places) depends on the standard you have agreed with the other party; round the result accordingly.
