Creating a Utilization% Gauge

Hey Everyone,
I am struggling to make a Utilization% Gauge, that will take in an amount of second and tell me what percentage of a 24 Hours that took. I would like the gauge to also work if I changed the timescale any arbitrary value, which is why I am assuming it would not work if I just set the range of the gauges to max out at one day.

Thanks for any insight you guys might have I really appreciate it, been stuck on this for a while now.
