not probally best practice but it works...thanks
It's not a terrible solution, but it isn't the best it could be. Filtering AWK's input by line number using sed is unnecessary; AWK can do that easily. Ditto for deleting a character from a string.
Code:
df -k "$fs" | awk 'NR==2 { sub(/%/, "", $4); print $4 }'
