Overview

The Speed converter supports conversions between various velocity and speed units used in different contexts, from scientific measurements to everyday travel speeds.

​
Import

import { SpeedUnitConverter, SPEED_UNIT } from 'univerto/speed'

​
Available Units

The SPEED_UNIT constant provides the following units:
  • METER_PER_SECOND - Meter per second (m/s)
  • MILLIMETER_PER_HOUR - Millimeter per hour (mm/h)
  • KILOMETER_PER_HOUR - Kilometer per hour (km/h)
  • MILE_PER_HOUR - Mile per hour (mph)
  • KNOT - Knot (nautical mile per hour)
  • FOOT_PER_SECOND - Foot per second (ft/s)
  • INCH_PER_HOUR - Inch per hour (in/h)

​
Usage

import { SpeedUnitConverter, SPEED_UNIT } from 'univerto/speed'

// Convert 100 km/h to mph
const mph = SpeedUnitConverter.from(100, SPEED_UNIT.KILOMETER_PER_HOUR)
  .to(SPEED_UNIT.MILE_PER_HOUR)
  .convert()

console.log(mph) // 62.137...

​
Common Conversions

​
Vehicle Speeds

// Highway speed limit (mph to km/h)
const speedLimit = SpeedUnitConverter.from(65, SPEED_UNIT.MILE_PER_HOUR)
  .to(SPEED_UNIT.KILOMETER_PER_HOUR)
  .convert() // 104.607

// Speed camera reading (km/h to mph)
const cameraSpeed = SpeedUnitConverter.from(120, SPEED_UNIT.KILOMETER_PER_HOUR)
  .to(SPEED_UNIT.MILE_PER_HOUR)
  .convert() // 74.565

// Track speed (m/s to km/h)
const trackSpeed = SpeedUnitConverter.from(25, SPEED_UNIT.METER_PER_SECOND)
  .to(SPEED_UNIT.KILOMETER_PER_HOUR)
  .convert() // 90

​
Aviation & Maritime

// Aircraft speed (knots to km/h)
const aircraftSpeed = SpeedUnitConverter.from(450, SPEED_UNIT.KNOT)
  .to(SPEED_UNIT.KILOMETER_PER_HOUR)
  .convert() // 833.4

// Ship speed (knots to mph)
const shipSpeed = SpeedUnitConverter.from(25, SPEED_UNIT.KNOT)
  .to(SPEED_UNIT.MILE_PER_HOUR)
  .convert() // 28.769

// Cruise speed (mph to knots)
const cruiseSpeed = SpeedUnitConverter.from(500, SPEED_UNIT.MILE_PER_HOUR)
  .to(SPEED_UNIT.KNOT)
  .convert() // 434.524

​
Scientific Measurements

// Meters per second to feet per second
const mpsToFps = SpeedUnitConverter.from(10, SPEED_UNIT.METER_PER_SECOND)
  .to(SPEED_UNIT.FOOT_PER_SECOND)
  .convert() // 32.808

// Feet per second to meters per second
const fpsToMps = SpeedUnitConverter.from(100, SPEED_UNIT.FOOT_PER_SECOND)
  .to(SPEED_UNIT.METER_PER_SECOND)
  .convert() // 30.48
