kgTot (Function)

This converts the input given in kilograms into tonnes.

Syntax

<DOUBLE> unitconversion:kgTot(<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 tonnes.		INT LONG FLOAT DOUBLE	No	Yes

Example 1

SELECT unitconversion:kgTot(1) AS tonnes;

This query uses the unitconversion:kgTot() function to convert the value of 1 kilogram into its equivalent value in tonnes. The conversion result is 0.001 tonnes.

Example 2

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

@info(name = 'massConversionQuery')
INSERT INTO OutputStream
SELECT mass_kg, unitconversion:kgTot(mass_kg) AS mass_tonnes
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 tonnes.

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

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