Hz to BPM Converter

Convert frequency in Hz to beats per minute using BPM = Hz × 60. Shows the equivalent Italian tempo marking (Largo / Andante / Allegro / Presto), plus a subdivision interpretation table — "if this Hz represents one cycle per 1/8 note, the tempo is X BPM."

Subdivision Interpretation: What Tempo Does This Hz Imply?

If one cycle = one…	Straight BPM	Dotted BPM	Triplet BPM	Straight Marking

Each row shows what tempo BPM your input frequency implies if the LFO completes one cycle per that note value. The musically-realistic interpretations are usually 1/4 to 1/8 range.

Common Frequencies and Their Implied Tempos

Frequency	BPM (1/4 sync)	Marking	Typical Use
0.1 Hz	6	Sub-musical	Drone, ambient sweep, very slow filter mod
0.5 Hz	30	Grave	Very slow LFO pad, atmospheric movement
1 Hz	60	Larghetto	1 beat per second; ballad tempo
1.4 Hz	~84	Andante	Resting heart rate, hip-hop
2 Hz	120	Allegro	Pop / rock standard, house
2.1333 Hz	128	Allegro	House music
2.3333 Hz	140	Allegro	Dubstep, hardcore
2.9 Hz	~174	Presto	Drum & bass
4 Hz	240	Prestissimo	Beyond traditional tempo / 1/8 sync at 120
7.83 Hz	~470	Beyond music	Schumann resonance — well above music tempos
50 Hz	3,000	Beyond music	Mains hum EU (audible buzz)
60 Hz	3,600	Beyond music	Mains hum US

About Hz, BPM & LFO Sync

Hz (cycles per second) and BPM (beats per minute) are both measures of repetition rate, just with different time units. The conversion is direct: BPM = Hz × 60. A 1 Hz oscillation = 60 BPM (one beat per second). A 2 Hz oscillation = 120 BPM (the pop music standard). For frequencies above ~5 Hz, the implied tempos exceed traditional musical use, but the conversion still gives a useful "frequency in beat units" interpretation.

The killer use case: LFO sync

If you have a synth or effect with an LFO rate in Hz (not BPM), and you want it to lock to your project tempo, you need this conversion. A 2 Hz LFO synced to 1/4 notes = 120 BPM. The same 2 Hz LFO synced to 1/8 notes = 60 BPM. To 1/16 notes = 30 BPM. The subdivision table on this page makes this trivial.

Detected pulse / EKG to tempo

If you're analysing a pulse rate (heart, breath, gait) in Hz, this tool converts it to BPM directly. Resting heart rate ~1.0–1.3 Hz → 60–80 BPM. Brisk walking pace ~2 Hz → 120 BPM. Why bands love to play at 120 BPM — that's the natural step tempo for a walking person.

Tempo markings are aesthetic, not scientific

The Italian markings (Largo, Andante, Allegro, etc.) come from classical music tradition and have fuzzy boundaries. Different sources put them at slightly different BPM ranges. This tool follows a common modern convention (Andante 76–108, Moderato 108–120, Allegro 120–156, Presto 168–200). For frequencies beyond traditional music tempos (BPM > 300), no Italian marking applies; the tool labels these "Beyond music tempo".

Frequently Asked Questions

How do I convert Hz to BPM?

Multiply the frequency in Hz by 60. For example, 2 Hz × 60 = 120 BPM. 1 Hz = 60 BPM. 4 Hz = 240 BPM. The formula is simply "cycles per minute = cycles per second × 60", since there are 60 seconds in a minute.

What's the BPM of a 2 Hz LFO?

If "one LFO cycle = one beat" (1/4 sync): 120 BPM. If "one cycle = one 1/8 note": 60 BPM. If "one cycle = one 1/16 note": 30 BPM. If "one cycle = one whole bar" (4 beats): 480 BPM. The interpretation depends on how the LFO is supposed to align with your beat grid — use the subdivision table on this page.

Why is 7.83 Hz "beyond music"?

7.83 Hz × 60 = 470 BPM, which is far above the fastest traditional tempo (Prestissimo, typically capped around 200 BPM). Schumann resonance is a real physical phenomenon (Earth-ionosphere cavity mode) but isn't a musical tempo — it's an oscillation frequency in a different domain.

My LFO shows 0.5 Hz — is that musical?

0.5 Hz = 30 BPM, which is "Grave" — extremely slow but real. More commonly, 0.5 Hz is used as a tempo-synced LFO at 1 bar per cycle (= 120 BPM at 1/1 sync). A 0.5 Hz filter sweep on a 120 BPM track produces a smooth "open-close" movement once per bar.

Can I convert audio frequency to BPM?

Yes, mathematically. 440 Hz × 60 = 26,400 BPM. But this number is musically meaningless — audio frequencies are pitches, not beats. A 440 Hz tone is "A4" (a musical note), not a tempo. The conversion only makes practical sense for sub-audio frequencies (typically below ~10 Hz) used as LFOs, pulses, or modulation rates.

What's the BPM of a 60 Hz mains hum?

60 Hz × 60 = 3,600 BPM — far beyond any music tempo. But here's a fun fact: if you slowed the 60 Hz hum down to musical tempo (say, divide by 24 to land near 150 BPM), you'd get B1 (~62 Hz) shifted down to a beat at 2.5 Hz. Mains hum at 60 Hz is closer to a B1 note than a musical tempo.
