Conversions

Problem Description

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:

 

Input

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.

 

Output

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.

Sample Input

5

1 kg

2 l

7 lb

3.5 g

0 l

 

Sample Output

1 2.2046 lb

2 0.5284 g

3 3.1752 kg

4 13.2489 l

5 0.0000 g
