GNY07B - Conversions

no tags 

Conversion between the metric and English measurement systems is relatively simple. Often, it involves either multiplying or dividing by a constant. You must write a program that converts between the following units:

TypeMetricEnglish equivalent
Weight1.000 kilograms2.2046 pounds
0.4536 kilograms1.0000 pound
Volume1.0000 liter0.2642 gallons
3.7854 liters1.0000 gallon


The first line of input contains a single integer N, (1 ≤ N ≤ 1000) which is the number of datasets that follow.

Each dataset consists of a single line of input containing a floating point (double precision) number, a space and the unit specification for the measurement to be converted. The unit specification is one of kg, lb, l, or g referring to kilograms, pounds, liters and gallons respectively.


For each dataset, you should generate one line of output with the following values: The dataset number as a decimal integer (start counting at one), a space, and the appropriately converted value rounded to 4 decimal places, a space and the unit specification for the converted value.


1 kg
2 l
7 lb
3.5 g
0 l

1 2.2046 lb
2 0.5284 g
3 3.1752 kg
4 13.2489 l
5 0.0000 g

I was getting WA all the time then I used ( printf("%.4f",variable) ) to print (0.0000) insted of (0) for the 5th testcase and got AC

am too getting different answer incase of gal/litres.. is there anything wrong in outputset???

Fahd Shariff: 2010-04-18 23:01:26

Dividing or multiplying gives different results for gallons/liters.

Example: 1000 g = 3785.4000 l (by multiplying: 1000 * 3.7854)
or 1000 g = 3785.0114 l ( by dividing: 1000/0.2642)

What is the expected answer for 1000 g?
