## What is Ultra Measure Master?

Professional Grade U.S. Standard to Metric Conversion Calculator by Calculated Industries

The Ultra Measure Master® app from Calculated Industries gives you the power to solve metric and standard unit conversions on your iPhone and iPad.  And while perhaps obvious, if you change from an iOS device to a non-iOS device, you WILL need to buy a new license as they are incompatible.

Forget complex scientific calculators, memorizing conversion formulas or using tables — instantly calculate with more than 400 conversion combinations using 60 built-in standard and metric units. The Ultra Measure Master is especially helpful for those working in federal DOT environments where frequent metric to foot-inch conversions and “dual unit” reporting is required -- and includes a full User’s Guide built in as well as the ability to press and hold a key for specific help!

Ideal for Engineers, Architects, Designers, Contractors/Builders, Draftspersons, Excavation/Highway Contractors, Scientists, Pharmaceutical Lab Techs, Purchasing, Importers/Exporters, Students (or anyone who needs fast, easy, professional unit conversions).  

•    Work in and convert between all building dimensional formats: feet-inch-fractions, inch fraction,      yards, decimal feet (10ths, 100ths), decimal inches and metric (m, cm, mm)
•    Easily calculate linear, area and volume measurements
•    Find dry and liquid weight per volume
•    Solve for velocity, flow rate, pressure, temperatures

### 5/5 — Architect, love this app

*2022-02-04*

Years ago, I replaced my failing physical calculator with this app and have never looked back. 
Always with me. Reliable. 
As an Architect, I use it a lot. 
Love it.  👍🏼

### 5/5 — Must have

*2019-07-29*

Use it everyday.  It does exactly what you pay for and no more. Ever app dev should take a lesson from Calc Ind.  really impressed with all their calculators.

### 5/5 — Love it

*2017-06-26*

Super easy to use, strongly recommended!!!!!!!!!!

### 4/5 — This app make a job done.

*2016-10-19*

I'm using this app for about 3 years and and it's helps a lot on my job which is structural design engineering. Easy to use, fast to do finish tasks on time. 
P.S. For developers. 
Please update performances for iOS 10. iPhone keeps notifying me that app slows down performances of the phone. Thanks.

### 5/5 — Best app ever!!

*2013-12-08*

I love this app! I know someone with a real measure master calculator that I was always borrowing, now I can carry one with me wherever I go. I do a lot of additions with standard measurements, and this thing makes them as easy as metric addition!!! Lol. Love the setting where you can pick the level of accuracy to round your inches off to, 1/16, 1/32, etc.

### 5/5 — Great tool

*2011-03-08*

I have one of these calculators at work I paid 45 bucks on sale and use it everyday to figure volumes and conversions I love the fact that for 5 bucks I can have that on me at all times just in case I misplace the calculator and it works great for home use as well. The only thing it doesn't do is rotate but hey It does everything else perfectly.

### 1/5 — Ultra Measure Master

*2010-12-29*

I have the actual calculator and needed / wanted the same for my new iPad. What a real disappointment - the two are NOT the same. The iPad version does not include the shift key, square key, cubic key, etc. I just wasted $4.99. Also, the iPad version is small and does not rotate when the iPad rotates.

### 5/5 — Looking Good thus far.

*2010-09-06*

I am unlikely to need to make conversions using Gallons, assuming these will be USA rather than UK variety, so this app should do everything needed.
Great display with nice big ‘keys’ and a good use of the valuable space gained by blocking out the iPhone’s top menu bar.
