One of the main considerations when building or buying a drone is flight time. Yet, although it’s such an important factor, it’s actually quite hard to calculate. Our simple flight time calculator isn’t designed to accurately predict flight time down to the second, but it should help you to quickly get a ballpark idea of what you can expect from your setup.
The calculator requires input values for: battery capacity (Ah), discharge (%) and average amp draw (A).

The one I am using is next one below. It is designed for multicpters, planes, helicopters and is very accurate.

If I have 1 Ah for 100% disharge and 1A of Average Amp Draw.
Result is.. 60 minutes.
Huhu, what a surprise! :D
Here's another flight time calculator, the one I usually use. This one allows a bunch more inputs:
