## h3DegsToRads {#h3degstorads}
Converts degrees to radians.
**Syntax**
``` sql
h3DegsToRads(degrees)
```
**Parameter**
- `degrees` — Input in degrees. Type: [Float64](../../../sql-reference/data-types/float.md).
**Returned values**
- Radians. Type: [Float64](../../../sql-reference/data-types/float.md).
**Example**
Query:
``` sql
SELECT h3DegsToRads(180.0) AS radians;
```
Result:
``` text
┌───────────radians─┐
│ 3.141592653589793 │
└───────────────────┘
```
## h3RadsToDegs {#h3radstodegs}
Converts radians to degrees.
**Syntax**
``` sql
h3RadsToDegs(radians)
```
**Parameter**
- `radians` — Input in radians. Type: [Float64](../../../sql-reference/data-types/float.md).
**Returned values**
- Degrees. Type: [Float64](../../../sql-reference/data-types/float.md).
**Example**
Query:
``` sql
SELECT h3RadsToDegs(3.141592653589793) AS degrees;
```

``` text
┌─degrees─┐
│ 180 │
└─────────┘
```
## h3CellAreaM2 {#h3cellaream2}
