Regular Tetrahedron Volume Calculator
Enter a positive edge length to calculate ideal regular tetrahedron volume.
A QUICK WALKTHROUGH
How to use this tool
- Enter edge length in any consistent unit.
- Calculate the volume.
- Read the result in cubic units.
Formula and scope
For edge length a, volume V = a³/(6√2). The result is expressed in the cube of the input unit.
Ideal geometry
Assumes a regular tetrahedron with equal edges and ideal Euclidean geometry. Local calculation only.
GOOD TO KNOW
Common questions
What units are returned?
Cubic units matching the edge unit, such as cm³ if the edge is in cm.
