In metric prefixes for SI measurements:
Therefore, 25K is 25,000 units. You could also write 25k (lowercase k). These abbreviations are appropriate for summary text but not itemized lists or tables. In that case, should not abbreviate (although you may specify all numbers in thousands in the legend if appropriate).
