Paste data here. It stays in your browser.
Copy-ready result appears here.
How it works
- Reads a compact interval string.
- Maps m, h, d, and w units to milliseconds.
- Returns milliseconds, seconds, minutes, and hours.
Common use cases
- Configure exchange API clients.
- Build bot candle schedulers.
- Validate interval input in dashboards.
Code example
const intervalMs = 15 * 60 * 1000Interval normalization
Exchange APIs often use compact interval strings such as 1m, 15m, 1h, or 1d. Converting those intervals to milliseconds helps with polling, cache expiry, and scheduler code.
Development use
Use the result as a helper for bot code, not as a guarantee that an exchange supports every interval string.
