# xarray.coding.variables.CFScaleOffsetCoder

### *class* xarray.coding.variables.CFScaleOffsetCoder(decode_times=False, decode_timedelta=False)[[source]](https://github.com/pydata/xarray/blob/main/xarray/coding/variables.py#L505-L573)

Scale and offset variables according to CF conventions.

Follows the formula:
: decode_values = encoded_values \* scale_factor + add_offset
