Sample input/output:
<pre>
1 tochka
2 liniya
3 dyuim
4 vershok
5 piad
6 fut
7 arshin
8 sazhen
9 versta
10 milia
11 centimeter
12 meter
13 kilometer
Please choose a unit 1 to 13 : 13
Now enter a value in that unit : 1
The equivalent in the remaining units is:
tochka : 393700.78
liniya : 39370.08
dyuim : 3937.0078
vershok : 2249.7188
piad : 562.4297
fut : 328.08398
arshin : 140.60742
sazhen : 46.86914
versta : 0.9373828
milia : 0.13391183
centimeter : 10000
meter : 100
