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 | +-----------------------------------------------------+
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.
5 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
