자주 묻는 질문

›How do I convert Hz to RPM?

Multiply Hz by 60 — frequency in cycles per second × 60 seconds per minute = RPM. So 50 Hz = 3,000 RPM.

›What's the audible frequency range?

Roughly 20 Hz to 20,000 Hz (20 kHz) for young, healthy ears. The upper limit drops with age.

›Wi-Fi at 2.4 GHz vs 5 GHz?

5 GHz is faster and less crowded but has shorter range. 2.4 GHz penetrates walls better but is shared with microwaves and Bluetooth.

›BPM for resting heart rate?

Adult resting heart rate is typically 60-100 BPM. Athletes often hit 40-60 BPM.

›Is the converter free?

Yes — free, no signup, runs in your browser.
