How many steps is 30 minutes of cycling?

I'm curious, could you please clarify for me: How exactly does one convert the duration of cycling, specifically 30 minutes, into the number of steps taken? Is there a standard formula or method that one can use to make this calculation, or does it vary depending on factors such as the cyclist's speed, the terrain, and the type of bike being used? Additionally, are there any online tools or apps that can assist in making this estimation, or is it a more manual process that involves tracking one's cycling session in real-time?
