These calculators from Allen Lim, PhD are based on his several years of research and expertise in the science of training with power. Try them out and see where your fitness is at.
Here is one version of a power vs time calculator based on one's best 10 minute power. It is meant to calculate peak aerobic power outputs and is not necessarily accurate for durations under 10 minutes. Get a reference for what your peak power outputs are for different time frames.
* Input best 10 minute Power: watts.
* Input time of interest: minutes (10 minutes or more).
