# cf.cellsize

`cf.``cellsize`(value, units=None)

  Return a `cf.Query` object for the cell size of a coordinate object.

  In this context, a coordinate is any object which has a `cellsize` attribute.

  If value is a `cf.Query` object then `cf.cellsize(value)` is equivalent to `value.addattr('cellsize')` (see `cf.Query.addattr`). Otherwise `cf.cellsize(value)` is equivalent to `cf.eq(value, attr='cellsize')`.

  Parameters: | value: Either the value that the cell size is to be compared with, or a `cf.Query` object for testing the cell size.
  Returns: | out: `cf.Query` The query object.
  Examples: |

      >>> cf.cellsize(cf.lt(5, 'km'))
      <CF Query: cellsize(lt <CF Data: 5 km>)>
      >>> cf.cellsize(5)
      <CF Query: cellsize(eq 5)>
      >>> cf.cellsize(cf.Data(5, 'km'))
      <CF Query: cellsize(eq <CF Data: 5 km>)>
      >>> cf.cellsize(cf.Data(5, 'km'))
      <CF Query: cellsize(eq <CF Data: 5 km>)>
      >>> cf.cellsize(5, units='km')
      <CF Query: cellsize(eq <CF Data: 5 km>)>
