Units is a really useful app that lets you easily convert from various units into lots of others.

NEW: Units now supports doing quick conversions on Apple Watch. Perfect for currency conversions on holiday, or any other calculations you need to do quickly throughout your day.

Units can convert hundreds of units from 43 different categories including Speed, Time, Length, Volume, Area, Power, Temperature, Fuel Consumption, Shoe Sizes and loads more!

Units is now a fully universal app with native support for iPhones, iPod touches and iPads.

As an added bonus, Units also has a built in ruler, for doing small, quick measurements when the need arrises.

• Convert hundreds of units - Units has over 800 units across 43 different categories.
• Convert currency - Units can convert between 88 different currencies, with rates updated daily.
• Hide unused units - Units lets you hide units you don't use, allowing you to maintain a streamline conversion workflow.
• Reorder units & categories - Units Premium allows you to reorder units and currencies however you want them.
• Built in ruler - Units has a built in ruler allowing you to make small, quick measurements without carrying round a ruler.

Units Premium disables adverts and allows you to reorder both units and unit categories to suit your needs.

Ratings and Reviews

Stability issues fixed - now very functional


Very functional, now stable, and had a great range of units.

I gave the last version a bad review due to stability issues compared to old free (and no ads) version. However developer has fixed it and seems to work fine now.

It is certainly not an example of a pretty user interface, but it is clear and functional. The huge range of units (including grains, drachm, etc) is great.

I now recommend it again.



great App...EXCEPT... on my iPad in PORTRAIT view the Units column is NOT shown so you cannot change from one set of conversions to another.
You must always use this App in LANDSCAPE mode. Please fix this.



The app crashes regularly when reordering items.
