Convert Requests Per Second to Per Minute
Learn how to convert API rate limits from requests per second (RPS) to requests per minute (RPM) and other time units. Essential for comparing API limits across services.
Detailed Explanation
Requests Per Second to Per Minute Conversion
The most basic rate limit conversion multiplies or divides by the number of seconds in the target time unit. If an API allows 10 requests per second, that translates to:
| Unit | Calculation | Result |
|---|---|---|
| Per second | 10 | 10 RPS |
| Per minute | 10 x 60 | 600 RPM |
| Per hour | 10 x 3,600 | 36,000 RPH |
| Per day | 10 x 86,400 | 864,000 RPD |
| Per month (30d) | 10 x 2,592,000 | 25,920,000 |
Why This Conversion Matters
Different APIs express their rate limits in different units. Stripe uses requests per second, GitHub uses requests per hour, and Twitter uses requests per month. To compare them fairly or to design a system that calls multiple APIs, you need a common unit.
Practical Tip
When converting from a larger unit (e.g., per hour) to a smaller unit (e.g., per second), keep in mind that most rate limiters do not allow you to use all your hourly quota in the first second. The per-second equivalent is the sustained average rate, not the allowed burst rate.
Use Case
You are designing a microservice that calls both the Stripe API (100 requests/second) and the GitHub API (5,000 requests/hour). You need to express both limits in the same unit to calculate how many parallel workers you can run without exceeding either limit.
