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:

 

TypeMetricEnglish equivalentWeight1.000 kilograms2.2046 pounds 0.4536 kilograms1.0000 poundVolume1.0000 liter0.2642 gallons 3.7854 liters1.0000 gallon

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.
