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:

Type Metric English equivalent
Weight 1.000 kilogram 2.2046 pounds
0.4536 kilograms 1.0000 pound
Volume 1.000 liter 0.2642 gallons
3.7854 liters 1.000 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.
