What this converter does
This converter turns hertz into beats per minute and back instantly. One hertz is one cycle per second, which is 60 beats per minute — the way to read an LFO or delay rate back into a musical tempo. Type a value and read it as you type.
It also relates to rpm on the same per-minute base. For rotating machinery, see the Hz to RPM converter.
02
The units it covers
Beats and cycles are both per-time rates, so they convert through the hertz — 60 BPM equals 1 Hz.

| Unit | Symbol | Value | Mainly used |
|---|---|---|---|
| Beats per minute | BPM | 0.01667 | Music tempo, heart rate |
| Hertz | Hz | 1 | Cycles per second |
| Beats per second | BPS | 1 | Same as hertz |
| Revolutions per minute | rpm | 0.01667 | Rotational rate |
03
The formula
Each rate has a fixed value in hertz, so any pair converts through the hertz:
Conversion
result = value × factor_from ÷ factor_toWhere:
- value = the number you typed
- factor_from = the “from” unit’s value in Hz
- factor_to = the “to” unit’s value in Hz

Worked example
Convert 2.5 Hz to BPM.
Step 1 · The relation
1 Hz = 60 BPMStep 2 · Multiply
2.5 × 60 = 150 BPMSo a 2.5 Hz rate is a tempo of 150 BPM.

The units in this example
Hertzsymbol: Hz
Cycles per second — the SI frequency unit used for LFOs, filters and signals.
Common tempo conversions
- 1 Hz = 60 BPM
- 2 Hz = 120 BPM
- 0.5 Hz = 30 BPM
- 1 Hz = 1 BPS
Beats per minutesymbol: BPM
The tempo of music or a heart rate — beats counted over one minute.
Common tempo conversions
- 60 BPM = 1 Hz
- 120 BPM = 2 Hz
- 1 BPM = 0.01667 Hz
- 140 BPM ≈ 2.33 Hz

FAQ
QHow many BPM is 2 Hz?
120 BPM. Multiply hertz by 60, so 2 Hz = 120 BPM.
QIs 1 Hz 60 BPM?
Yes. One cycle per second equals 60 beats per minute.
