# Multiply Measures by a Fixed Amount

You can multiply the values of a measure or derived measure by a fixed amount. For example, you can use the multiplier to convert a field’s decimal values to percents.

In this example lens, the values in the Discount column are shown as decimal values.

To change the decimal value to a percentage, modify the XMD file as shown in this example. Add “%” after the value, and change the field label to "Discount %".

```nolang
{
  “Measures” : [
    {
      "field": "Discount",
      "format": {
        "customFormat": "[\"##.##%\",100]"
      },
      "label": "Discount %",
      "showInExplorer": true
    }
],

```

The Discount column now has the label Discount %, and the values are in percentages.

:::note
If a measure field has a multiplier of “0”, downloading the data to an `.xls` or `.csv` file results in all values for that field displaying as “0”. A “0” multiplier has this format: `"format":{"customFormat":"[\"#,###\",0]}`.
