Hz to BPM Converter
Convert frequency in Hz to beats per minute using BPM = Hz × 60 — a direct frequency-to-tempo conversion. 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."

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. To go the other direction — starting from a tempo and finding the matching frequency for each note value — use the BPM to Hz converter which generates a full delay-time table.
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, this LFO-to-BPM calculation is exactly what you need. 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. The same principle applies to tremolo and vibrato rates: a guitar amp's tremolo speed dial is often calibrated in Hz, and converting it tells you which note value its wobble locks to at a given tempo. A rate of 4 Hz at 120 BPM, for example, is a 1/8-note tremolo (4 Hz × 60 ÷ 4 subdivisions per beat = 60 BPM quarter-note equivalent). For hearing a reference pitch at a specific musical frequency, the online tone generator lets you dial in any Hz directly.
Detected pulse / EKG to tempo
If you're analysing a pulse rate (heart, breath, gait cycle) 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. This is also why many bands gravitate to 120 BPM — it matches the natural step cadence of a walking person. In electronic music production the same math applies to sidechain pump rate: a kick drum at 2 Hz (120 BPM) pumps a compressor at exactly 1/4-note rate.
Tempo markings are aesthetic, not scientific
The Italian markings (Largo, Andante, Allegro, etc.) come from classical music tradition and have fuzzy boundaries that vary by era and publication. Different authoritative sources place 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". If you need to verify an unknown song's tempo, the BPM tap tool lets you tap along to determine it by ear.
