Unit converter v2.4 (for package)

Hello. I'm android boy, working for Smart Tools co.,

Unit Converter pro is ad-free version with more features. Ads are replaced with useful messages(formula, unit name). This article shows instructions for package version.

I'm sorry that currency exchange rates feature was removed because of the lack of internet permission.

※ Unit sections
 ① Basic : length (distance), area, weight (mass), volume (capacity)

 4) Tap number input box, enter numbers with the keypad

Toggle checkboxes in the order you want (①-②-③-④).

※ How to input fractions
In length and weight sections, this app has [. /] button on the keypad. You can input fractions with it.

ex1) 5 1/4 =>  [5] + [./] + [1] + [./] + [4]
ex2) 3/8 = 0 3/8 => [./] + [3] + [./] + [8]   (Look out!! 3/8 is less than 1.)
       or [3] + [./] [./] + [8]


※ How to input "ft and inch" at the same time
Select "ft in" unit. For various inputs, you can use fractions. "lb oz" are the same.

ex1) 2' 3.5" =>  [2] + [ ' "/ ] + [3] + [ ' "/ ] + [5]
ex2) 1' 2 5/8" => [1] + [ ' "/ ] + [2] + [ ' "/ ] + [5] + + [ ' "/ ] + [8]


※ How to input "deg min sec"
Select "deg min sec" or "deg" unit in angle section. You can input "deg min sec" with [.˚ '] button on the keypad.

ex1) 1˚ 23' 45.67" =>  [1] + [.˚'] + [2][3] + [.˚'] + [4][5] + [.˚'] + [6][7]
ex2) 0˚ 1' 2" =>  [.˚'] + [1] + [.˚'] + [2]


※ Data storage / flow ?
The app shows data storage and data flow in data section so as to save a tab. It is not a mistake. Similarly, it shows speed and running face units in speed section, too. By the way, do you know the difference of "kb", "kB", "kib", "kiB", "kbps"?
 b : bit
 B : byte
 k : kilo (1000)
 Ki : kibi (1024)
 M : mega (1000 x 1000)
 Mi : mebi  (1024 x 1024)
 kbps : kilo bit per second

It supports landscape mode for tablet PCs. Select more menu (3 dots) at the top-right corner.


 FAQ
Q. How to copy the number to clipboard?
A. Double-tap on the number (since v2.4.2)

Q. How can I convert from gram to litre?
A. "gram" is weight unit, "litre" is volume unit. They cannot be converted. Water 1kg = 1L, gasoline 1kg = ~0.70L

Q. Where is "A(amp)" unit?
A. Click the favorite icon (star) in Science category. Select [Current] checkbox.

Q. "kg" is not weight unit, but mass unit.
A. I know. weight = mass x Gravity. "mass" and "weight" are same in earth.
Above all, "weight" is a friendly word and the public do not understand "mass" perfectly.
