What Is This Tool?

This converter transforms speed values from centimeters per hour (cm/h), a unit for very slow speeds used in fields like hydrogeology and engineering, into the velocity of light in vacuum, the fundamental constant representing the maximum speed possible in the universe.

How to Use This Tool?

  • Enter the speed value in centimeters per hour.
  • Select 'centimeter/hour [cm/h]' as the input unit.
  • Choose 'velocity of light in vacuum' as the target unit.
  • Click convert to obtain the speed expressed as a fraction of the speed of light.

Key Features

  • Converts linear speed from cm/h to velocity of light in vacuum accurately.
  • Easy to use in scientific and engineering applications for comparing extremely slow speeds to light speed.
  • Browser-based unit converter requiring no installation.
  • Provides precise expression of slow speeds as fractions of the universal speed limit.

Examples

  • 10 cm/h equals 9.2656693110598e-14 times the velocity of light in vacuum.
  • 100 cm/h corresponds to 9.2656693110598e-13 times the velocity of light in vacuum.

Common Use Cases

  • Measuring very slow groundwater or soil seepage rates in hydrogeology.
  • Quantifying creep or slow deformation rates in geotechnical monitoring.
  • Reporting low-speed motions in precision laboratory instrumentation.
  • Converting slow speeds to fractions of light speed for astrophysical and physics research.

Tips & Best Practices

  • Use this converter for scientific or theoretical scenarios requiring high precision.
  • Keep in mind the extremely small conversion factor when interpreting results.
  • Avoid using velocity of light units for everyday speed measurements due to impracticality.
  • Confirm unit selections carefully to ensure accurate conversions.

Limitations

  • The velocity of light unit has a very small conversion factor from cm/h, making it unsuitable for typical speed uses.
  • Interpreting slow speeds as fractions of light speed may be challenging due to vast magnitude differences.
  • Primarily intended for theoretical, scientific, and precision measurements rather than practical applications.

Frequently Asked Questions

Why convert cm/h to the velocity of light in vacuum?
Converting slow speeds to the velocity of light provides a reference against the universal speed limit, useful in advanced scientific and engineering contexts for precision and comparative analysis.

Is velocity of light a convenient unit for everyday speeds?
No, because the conversion factor is extremely small, velocity of light is impractical for daily speed measurements, and mainly used in scientific research.

What fields commonly use this conversion?
Fields like hydrogeology, geotechnical engineering, astrophysics, and precision instrumentation use this conversion to analyze slow speeds relative to light speed.

Key Terminology

Centimeter per hour (cm/h)
