kgTolb (Function)

This converts the input given in kilograms into pounds.

Syntax

<DOUBLE> unitconversion:kgTolb(<INT|LONG|FLOAT|DOUBLE> p1)

Query Parameters

Name	Description	Default Value	Possible Data Types	Optional	Dynamic
p1	The value that needs to be converted from kilograms into pounds.		INT LONG FLOAT DOUBLE	No	Yes

Example 1

unitconversion:kgTolb(1)

In this example, the unitconversion:kgTolb() function converts a value of 1 kilogram into its equivalent value in pounds. The conversion result is approximately 2.2 pounds.

Example 2

CREATE STREAM InputStream (mass_kg double);
CREATE SINK STREAM OutputStream (mass_kg double, mass_lb double);

@info(name = 'massConversionQuery')
INSERT INTO OutputStream
SELECT mass_kg, unitconversion:kgTolb(mass_kg) AS mass_lb
FROM InputStream;

In this example, an input stream called InputStream is created with a single attribute, mass_kg, representing mass values in kilograms. Then, an output stream called OutputStream is defined, which will contain the original mass in kilograms as well as the converted mass in pounds.

The massConversionQuery processes events from the InputStream. It uses the unitconversion:kgTolb() function to convert the mass_kg attribute from the InputStream into its corresponding value in pounds, and this value is assigned to the mass_lb attribute in the OutputStream.

The query outputs the original mass in kilograms and the converted mass in pounds for each event to the OutputStream.
