If you're an Engineer,
A Scientist,
A Researcher,
Or just like Measuring Things
You can use Frank Harr's Conversion App!

So, what makes it so special?

It's relatively small, doesn't need access to the internet, doesn't collect user data and has no ads and no in-app purchases.

That's not special.

It is the singular expression of one person's concept of how unit conversions should work.

Not special enough.

It represents at least 29 systems of measurement:
* 15/59 Degrees,
* Absolute English
* Bangladeshi,
* British Gravimetric,
* Burmese/Myanmarese,
* cm-g-s,
* English Engineering,
* Gaussian,
* Gravitational Metric,
* HLU,
* Hong Kongese,
* Imperial,
* Indian Survey,
* International Steam Table (1956),
* The International Yard and Avoirdupois Pound
* ISO Steam Table,
* Japanese,
* Logarithmic,
* m-kg-s,
* m-t-s,
* Nepalese,
* Nautical,
* SI,
* Taiwanese,
* Thai,
* Thermochemical,
* U.K. 1995,
* U.S. Customary,
* U.S. Survey and even some not-quite systems.

That's a little special.

It has units measuring 39 properties:
* Length,
* Speed/Velocity,
* Acceleration,
* Area,
* Capacity/Volume,
* Flow,
* Mass,
* Density,
* Temperature,
* Force,
* Pressure,
* Torque,
* Time,
* Probability,
* Energy/Work,
* Energy Distribution,
* Power,
* Thermal Resistance
* Plane and Solid Angles,
* Dynamic Viscosity,
* Fluidity,
* Kinematic Viscosity,
* Charge,
* Current,
* Voltage/Electrical Potential,
* Electric Field,
* Magnetic B and H fields, Moment and Flux,
* Resistance,
* Resistivity,
* Capacitance,
* Inductance,
* Luminance,
* Illuminance,
* Radioactive Source Activity and
* Fractions, Groups and Levels

That's a little more special. But still.

But there's more! Most conversion apps only deal with one unit at a time forcing people to convert feet and inches into just feet or just inches or converting pounds and ounces into just pounds or just ounces. But this will let you use inches with feet, ounces with pounds, furlongs with miles!

That's even more special.

And there's STILL more! This does fractions!


Yes, fractions! What if you want to know how many sevenths of something there is? Or if you can measure to an eighth of something? Fractions are useful and decimal inches and pounds are a crime against nature.



O.K., that is special. How much?

But there's still more!


You can convert not just units, but ratios too. So you can convert liters per kilometer to miles per gallon or meters per megawatt to feet per horsepower!

I've always wanted to do that!

I KNOW! Me too! And you can even create and use your own units.

What's new

Well, I couldn't get the new feature done on time. But, that's no reason to not go forward. There is some behind the scenes improvement. Minore improvements are important too.
