Overview
This Frequency Converter instantly converts any frequency value between dozens of supported units including Hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz), as well as practical units like rpm (revolutions per minute), rps (revolutions per second), and rare scientific formats like cycles per day (cpd), cycles per year (cpy).
It’s a powerful tool for electrical engineers, audio technicians, mechanical designers, physics students, or anyone needing to analyze cycles per time unit. With Advanced Mode, you can unlock specialized formats for astronomy, biology, and climatology.
- 🔁 Convert audio frequencies (e.g., 440 Hz = A4 pitch)
- 🔬 Use MHz–THz for scientific equipment or wireless systems
- ⚙️ Convert rpm to Hz for rotating machinery
- 🌍 Handle exotic cycles/day or year-based systems (climate, biological rhythms)
Formula & Methodology
All frequency conversions use a two-step method centered around Hertz (Hz) as the base unit:
- Convert input → Hz using a predefined multiplier.
- Convert Hz → target unit using the reciprocal multiplier.
For example:
3000 rpm → Hz = 3000 ÷ 60 = 50 Hz 50 Hz → kHz = 50 ÷ 1000 = 0.05 kHz
Here's a conversion reference table:
| Unit | Equivalent in Hz | Notes |
|---|---|---|
| Hertz (Hz) | 1 | Base unit |
| Kilohertz (kHz) | 1,000 | Audio/electronics |
| Megahertz (MHz) | 1,000,000 | Radio, CPUs |
| Gigahertz (GHz) | 1,000,000,000 | WiFi, 5G |
| Terahertz (THz) | 1,000,000,000,000 | Far-infrared, imaging |
| rpm | 1/60 | Rotational speed |
| rps | 1 | Same as Hz |
| cpm | 1/60 | Cycles/minute |
| cph | 1/3600 | Cycles/hour |
| cpd | 1/86400 | Cycles/day |
| cpy | 1/31,536,000 | Cycles/year |
Examples
- 440 Hz → kHz: 440 ÷ 1000 = 0.44 kHz
- 2.4 GHz → Hz: 2.4 × 1,000,000,000 = 2,400,000,000 Hz
- 3000 rpm → Hz: 3000 ÷ 60 = 50 Hz
- 100 cpd → Hz: 100 ÷ 86400 ≈ 0.001157 Hz
- 0.5 THz → MHz: 0.5 × 10¹² ÷ 10⁶ = 500,000 MHz
Use Cases

- 📡 Wireless communication analysis (MHz ↔ GHz)
- ⚙️ Mechanical engineering: rpm/rps conversions
- 🧬 Biological cycle tracking (e.g., circadian rhythms in cpd)
- 🌌 Astronomical or seasonal phenomena measured in cpy
Frequently Asked Questions
What is frequency?
Frequency is the number of occurrences of a repeating event per unit time. The standard SI unit is Hertz (Hz), or cycles per second.
What’s the difference between Hz, rpm, and rps?
Hertz (Hz) measures cycles per second. Revolutions per minute (rpm) measures cycles per minute. Since 1 rpm = 1/60 Hz, simply divide rpm by 60 to get Hz.
Can I convert between GHz and MHz?
Yes. 1 GHz = 1000 MHz. Use this tool to quickly convert between any units like these.
Are cpd and cpy real units?
Yes. “Cycles per day” (cpd) and “cycles per year” (cpy) are used in climatology, biology, and astronomy.
What’s the highest frequency this tool supports?
Up to terahertz (THz), or 1 trillion Hz. Ideal for advanced physics and wireless system analysis.
Is this tool accurate and up-to-date?
Yes. All conversion factors are based on SI definitions and scientific standards, updated periodically.
Can I use the tool on mobile or offline?
Yes. It’s mobile-optimized and runs client-side. Once loaded, it works even without internet.
Why are “cycles per day/year” considered advanced?
Most everyday frequency conversions use Hz or kHz. Units like cpd (cycles/day) or cpy (cycles/year) appear in astronomy or climatology, so they’re tucked behind Advanced Mode.
