This is the full version and it is completely free!

This application converts between the most common Metric units and US Imperial units.

Emphasis on cooking!

The first four tabs are an easy to use conversion from Imperial to Metric for four categories.
- Distance
- Temperature
- Volume
- Weight

The last tab has a wheel which includes a large number of conversions.

What's New

Version 2.2

Corrected a typo. Added US quarts and UK quarts to the Other tab. Probably the last update for a while to prevent update fatigue. Send any feedback to support@devicestuff.com.

This is now my most useful app. I often have to convert milliters to fluid ounces and then again in reverse. I must know how much of an additive to add to engine lubricants, fuel cleaners and many other engine related equations. I know many others that will be very greatful to have this much needed tool on their phone. Thank you so much for creating this app, I very much appreciate it. I would gladly have paid for it. This is very refreshing because there are so many bad apps out there.

Great app, until Apple’s recent update ruined our collective user experience


I relied on this app for years, but unfortunately Apple’s most recent update has made it impossible to use the app unless the developers update what would otherwise be a fully-functional app to accommodate whatever minor, control-freak-ish tweak they’ve put in the most recent iOS. Goddang it, Apple.

Nice layout, simple to use. Ads.

The things you need to convert most are right up front and easy to get at. The developer is making their
money via the ads; nothing wrong with that. But downloading the ads uses up your battery faster, so what would be a 4 star rating from me is deducted one star. I would like the option of an ad-free paid version.
