This is 1024 bytes right?

Free space in f_frsize units = 1795
So free space would be (1795*1024)bytes.
Am I correct here?
That is correct.

This is the sector size. Data transfer size of the physical
storage media.

Minimum size of storage the file system will allocate when
writing new
data. Will be multiples of block size.

f_frsize is allocation unit size
