Frequently Asked Questions
How many atoms are in each unit cell?
A face-centered cubic cell has 4 atoms, a body-centered cubic cell has 2, and a simple cubic cell has 1. Other structures can be entered as a custom value.
What units does the edge length use?
Enter the cubic edge length in picometers. The calculator converts it to centimeters internally to return density in grams per cubic centimeter.
Why compare calculated and measured density?
A match confirms the assumed crystal structure, while a mismatch can reveal vacancies, impurities, or a different packing arrangement.
