Calculate granular-soil relative density from maximum, in-place, and minimum dry unit weights.
A QUICK WALKTHROUGH
How to use this tool
- Enter finite values in consistent units.
- Review the stated formula and input definitions.
- Calculate locally in this browser.
Formula and limits
Dr = (1/γd − 1/γd,max)/(1/γd,min − 1/γd,max). Result is reported as a percent; require γd,min < γd < γd,max.
Scope
