What Is This Tool?
This online unit converter facilitates the transformation of speed values from centimeter per hour, a unit measuring very slow linear speeds, to the third cosmic velocity, which represents the minimum speed necessary to escape the Solar System’s gravitational influence from near Earth’s orbit.
How to Use This Tool?
-
Enter the speed value in centimeter per hour (cm/h) in the input field
-
Select 'centimeter/hour [cm/h]' as the original unit
-
Choose 'Cosmic velocity - third' as the target unit
-
Click convert to obtain the equivalent value in Cosmic velocity - third
-
Use the result for aerospace or astrophysics applications

-
1000 centimeter/hour [cm/h] equals 1.6663333999867e-7 Cosmic velocity - third
Common Use Cases
-
Measuring very slow groundwater or soil seepage velocities in hydrogeology
-
Quantifying slow deformation or creep rates in structural monitoring
-
Calculating hyperbolic excess velocity for spacecraft leaving the Solar System
-
Planning interstellar probe missions such as Voyager or Pioneer trajectories
-
Studying dynamical behaviors of comet or asteroid ejection from the Solar System
Tips & Best Practices
-
Understand the vastly different scale of these units before converting
-
Use the tool to relate very slow terrestrial speeds to extreme celestial velocities
-
Apply results primarily in aerospace and astrophysical contexts
-
Verify unit selections carefully due to the non-intuitive conversion scale
Limitations
-
Units represent drastically different speed scales, resulting in extremely small conversion values
-
Centimeter/hour captures extremely slow speeds, while Cosmic velocity - third corresponds to very high escape velocities
-
Direct practical equivalence is limited due to differing application contexts
-
Conversion is mainly theoretical for comparison rather than everyday use
Frequently Asked Questions
-
What does the unit 'centimeter/hour' measure?
-
It represents a very slow linear speed showing how many centimeters an object travels in one hour, typically used in fields like hydrogeology and structural monitoring.
-
What is the third cosmic velocity?
-
It is the minimum velocity required for an object near Earth's orbit to escape the Sun’s gravitational pull entirely, used in planning interstellar spacecraft trajectories.
-
Why are the converted values so small when moving from centimeter/hour to Cosmic velocity - third?
-
Because centimeter/hour measures extremely slow speeds, while the third cosmic velocity is extremely high, making the conversion results very small numerically.
Key Terminology
-
Centimeter/hour [cm/h]
-
A unit expressing how many centimeters an object travels in one hour, used for very slow speeds in scientific fields.
-
Cosmic velocity - third
-
The minimum speed necessary for an object near Earth’s orbit to escape the Sun’s gravity and leave the Solar System.
-
Third cosmic velocity
-
Another name for the Cosmic velocity - third, significant for planning interstellar flight trajectories.
