Why the number is rounded over ssh?

Question

localhost:~ $ df -k / | awk '{print $3/1024/1024/1024}'
0
0.00618061

localhost:~ $ ssh localhost "df -k / | awk '{print $3/1024/1024/1024}'"
01
01

$3 is being substituted in your shell, before ssh sees it. — Michael Homer, Jul 24 '15 at 07:22
@MichaelHomer is right - what your localhost sees is df -k / | awk '{print /1024/1024/1024}' — amisax, Jul 24 '15 at 07:27

You need more quoting when you pass arguments to SSH. Try this:

ssh localhost "df -k / | awk '{print \$3/1024/1024/1024}'"
0
0.00623375

Note the \ before $3.
