Official Description  

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

Units can convert hundreds of units from 43 different categories including Speed, Time, Length, Volume, Area, Power, Temperature, Fuel Consumption, Clothing & 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 arises.

• 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 work flow.
• Built in ruler – Units has a built in ruler allowing you to make small, quick measurements without carrying round a ruler.”1

Thumbs Up

  • cost is free
  • no registration or sign-in required
  • easy and logical to use without any instruction
  • visually looks good
  • 44 different categories available, many more than similar apps
  • the categories of most value to EHS professionals include: computer data, currency, illumination, length, mass/weight, prefixes & suffixes, temperature, volume & dry capacity, and volume & liquid capacity
  • super fast calculations
  • a premium version is available for $.99 – it disables advertisements and allows you to re-order both units and unit categories
  • can “switch interface” to have both “categories” and “conversions” appear on the same screen
  • there have been prior complaints about “crashing” – but we experienced no crashes with the latest version (2.2.4)
  • we tested numerous other unit conversion apps – this is the best one we found

Thumbs Down

  • there’s a small and distracting advertisement at the bottom of the page on the free app
