Hey Product Hunt! I'm Janine, the maker of Uniport.

I've worked in cross-border e-commerce for almost ten years, and I still find myself looking up the same things: centimeters to inches, kilos to pounds, box volume, exchange rates, and meeting times across time zones.

I made Uniport to put those everyday conversions in one place.

The part I'm most excited about is batch product specs. Paste spreadsheet rows with dimensions and weights, convert them together, and copy English specifications into your listing. You can process up to 500 rows at a time, with an optional SKU on each row.

It also helps you:

- Calculate total box volume in cubic feet and CBM.

- Check daily reference exchange rates, with the source and date shown.

- Convert meeting times for a specific date, including daylight saving changes.

- Convert length, weight, liquid volume, and temperature.

It's free to use, works in English and Chinese, and doesn't require an account. Product specifications are processed in your browser rather than uploaded to a server.

I'd especially love feedback from people who work with suppliers or sell internationally: which conversion or copy-and-paste task keeps interrupting your day?

Try a couple of product rows and tell me where it helps, or where it gets in your way. Thanks for taking a look!
