If a service receives exactly 1 Million requests per day, what is the approximate Requests Per Second (RPS) during a steady load?

To calculate RPS, you divide total requests by total seconds in the day ($1,000,000 / 86,400$). Using the 100,000 approximation ($10^6 / 10^5$) gives you an instant estimate of 10 RPS. The precise answer is approximately 11.57 RPS. In a real-world system, however, load is rarely steady; engineers often double or triple this number to account for 'Peak RPS' during busy hours. Understanding this baseline allows you to size your server fleet and database capacity correctly before launching a new product.
