# Times (Spatial Analyst)

## Summary

Multiplies the values of two rasters on a cell-by-cell basis.

## Illustration OutRas = Times (InRas1, InRas2)

## Usage

• The order of inputs is irrelevant for this tool.

• If both inputs are integer, the output will be an integer raster; otherwise, it will be a floating-point raster.

• In Map Algebra, the equivalent operator symbol for this tool is "*" (link).

## Syntax

Times (in_raster_or_constant1, in_raster_or_constant2)
 Parameter Explanation Data Type in_raster_or_constant1 The input containing the values to be multiplied. A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. Raster Layer | Constant in_raster_or_constant2 The input containing the values by which the first input will be multiplied. A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment. Raster Layer | Constant

#### Return Value

 Name Explanation Data Type out_raster The output raster. The cell values are the product of the first input multiplied by the second. Raster

## Code Sample

Times example 1 (Python window)

This example multiplies the values of an input elevation raster by a constant value to convert the elevation values from feet to meters.

```import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outTimes = Times("elevation", "0.3048")
outTimes.save("C:/sapyexamples/output/outtimes")```
Times example 2 (stand-alone script)

This example multiplies the values of an input elevation raster by a constant value to convert the elevation values from feet to meters.

```# Name: Times_Ex_02.py
# Description: Multiplies the values of two rasters on a cell-by-cell basis.
# Requirements: Spatial Analyst Extension
# Author: ESRI

# Import system modules
import arcpy
