# Distance

The **Distance** function calculates the minimum distance between two geographies, in specified units.

You can use the **Distance** function on Snowflake and BigQuery connections.

**Distance** is one of Sigma's Geography functions.

## Syntax

Distance(units, geog1, geog2)

The function arguments are:

- units
- Required
- The unit of measurement for the distance
- Valid values are
`"kilometers"`

,`"meters"`

, and`"miles"`

. - geog1
- Required
- First geography of the pair between which we calculate the distance
- Must be in valid Geography format.
- To work from known latitude and longitude values, use the MakePoint or MakeLine functions.
- geog2
- Required
- Second geography of the pair between which we calculate the distance
- Must be in valid Geography format.
- To work from known latitude and longitude values, use the MakePoint or MakeLine functions.

## Examples

Distance("kilometers", [Coordinates], MakePoint(0, 0))

Distance("miles", [Coordinates], MakePoint(0, 0))

The **Distance** function returns the following values for the **Coordinates** column, when specifying distance in either kilometers or miles from coordinates (0, 0):
