Unit converter v2.3 (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 page is a manual for package version.

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

※ 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.)


※ 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" : select [ft in], input [2] + [ ' " ] + [3]
ex2) 5' 8.5" : select [ft], 5' 8.5" = 5 17/24', input [5] + [./] + [1][7] + [./] + [2][4]
ex3) 1' 2 5/8" : select [inch],  1' 2 5/8" =  14 5/8", input [1][4] + [./] + [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


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


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

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

A. "kg" is not weight unit, but mass unit.
Q. 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.
