Overview

The Frequency converter supports conversions between various frequency units, from slow oscillations in millihertz to extremely high terahertz frequencies, plus rotational measurements like RPM.

​
Import

import { FrequencyUnitConverter, FREQUENCY_UNIT } from 'univerto/frequency'

​
Available Units

The FREQUENCY_UNIT constant provides the following units: Standard Frequency Units:
  • MILLIHERTZ - Millihertz (mHz)
  • HERTZ - Hertz (Hz)
  • KILOHERTZ - Kilohertz (kHz)
  • MEGAHERTZ - Megahertz (MHz)
  • GIGAHERTZ - Gigahertz (GHz)
  • TERAHERTZ - Terahertz (THz)
Rotational Units:
  • RPM - Revolutions per minute
  • DEGREE_PER_SECOND - Degrees per second (°/s)

​
Usage

import { FrequencyUnitConverter, FREQUENCY_UNIT } from 'univerto/frequency'

// Convert 1000 Hz to kHz
const kilohertz = FrequencyUnitConverter.from(1000, FREQUENCY_UNIT.HERTZ)
  .to(FREQUENCY_UNIT.KILOHERTZ)
  .convert()

console.log(kilohertz) // 1

​
Common Conversions

​
Audio & Sound

// Middle A note (Hz to kHz)
const noteA = FrequencyUnitConverter.from(440, FREQUENCY_UNIT.HERTZ)
  .to(FREQUENCY_UNIT.KILOHERTZ)
  .convert() // 0.44

// Ultrasonic frequency (kHz to Hz)
const ultrasonic = FrequencyUnitConverter.from(40, FREQUENCY_UNIT.KILOHERTZ)
  .to(FREQUENCY_UNIT.HERTZ)
  .convert() // 40000

​
Radio & Communications

// FM radio (MHz to kHz)
const fmRadio = FrequencyUnitConverter.from(101.5, FREQUENCY_UNIT.MEGAHERTZ)
  .to(FREQUENCY_UNIT.KILOHERTZ)
  .convert() // 101500

// AM radio (kHz to MHz)
const amRadio = FrequencyUnitConverter.from(1500, FREQUENCY_UNIT.KILOHERTZ)
  .to(FREQUENCY_UNIT.MEGAHERTZ)
  .convert() // 1.5

// WiFi frequency (GHz to MHz)
const wifi = FrequencyUnitConverter.from(2.4, FREQUENCY_UNIT.GIGAHERTZ)
  .to(FREQUENCY_UNIT.MEGAHERTZ)
  .convert() // 2400

​
Computing & Processors

// CPU clock speed (GHz to MHz)
const cpuSpeed = FrequencyUnitConverter.from(3.6, FREQUENCY_UNIT.GIGAHERTZ)
  .to(FREQUENCY_UNIT.MEGAHERTZ)
  .convert() // 3600

// Memory frequency (MHz to GHz)
const memoryFreq = FrequencyUnitConverter.from(3200, FREQUENCY_UNIT.MEGAHERTZ)
  .to(FREQUENCY_UNIT.GIGAHERTZ)
  .convert() // 3.2

​
Mechanical & Rotational

// Engine speed (RPM to Hz)
const engineFreq = FrequencyUnitConverter.from(6000, FREQUENCY_UNIT.RPM)
  .to(FREQUENCY_UNIT.HERTZ)
  .convert() // 100

// Motor speed (Hz to RPM)
const motorSpeed = FrequencyUnitConverter.from(50, FREQUENCY_UNIT.HERTZ)
  .to(FREQUENCY_UNIT.RPM)
  .convert() // 3000

// Angular velocity (degrees per second to RPM)
const angularVel = FrequencyUnitConverter.from(360, FREQUENCY_UNIT.DEGREE_PER_SECOND)
  .to(FREQUENCY_UNIT.RPM)
  .convert() // 60

​
Scientific Applications

// Infrared light (THz to GHz)
const infrared = FrequencyUnitConverter.from(300, FREQUENCY_UNIT.TERAHERTZ)
  .to(FREQUENCY_UNIT.GIGAHERTZ)
  .convert() // 300000
