lTom3 (Function)

This converts the input given in liters into cubic meters.

Syntax

<DOUBLE> unitconversion:lTom3(<INT|LONG|FLOAT|DOUBLE> p1)

Query Parameters

NameDescriptionDefault ValuePossible Data TypesOptionalDynamic
p1The value that needs to be converted from liters into cubic meters.INT LONG FLOAT DOUBLENoYes

Example 1

SELECT unitconversion:lTom3(1000) AS cubic_meters;

This query uses the unitconversion:lTom3() function to convert the value of 1,000 liters into its equivalent value in cubic meters. The conversion result is 1 cubic meter.

Example 2

CREATE STREAM InputStream (volume_l double);
CREATE SINK STREAM OutputStream (volume_l double, volume_m3 double);

@info(name = 'volumeConversionQuery')
INSERT INTO OutputStream
SELECT volume_l, unitconversion:lTom3(volume_l) AS volume_m3
FROM InputStream;

In this example, an input stream called InputStream is created with a single attribute, volume_l, representing volume values in liters. Then, an output stream called OutputStream is defined, which will contain the original volume in liters as well as the converted volume in cubic meters.

The volumeConversionQuery processes events from the InputStream. It uses the unitconversion:lTom3() function to convert the volume_l attribute from the InputStream into its corresponding value in cubic meters, and this value is assigned to the volume_m3 attribute in the OutputStream.

The query outputs the original volume in liters and the converted volume in cubic meters for each event to the OutputStream.
