题目描述

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 kilograms         2.2046 pounds      |
+-----------------------------------------------------+
|          0.4536 kilograms        1.0000 pound       |
+-----------------------------------------------------+
|Volume    1.0000 liter            0.2642 gallons     |
+-----------------------------------------------------+
|          3.7854 liters           1.0000 gallon      |
+-----------------------------------------------------+

输入

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.

输出

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.
