Sectional density is often used in [[Ballistics#Gun_ballistics|gun ballistics]] where sectional density is the ratio of a [[projectile]] [[weight]], to its [[diameter]].
 
==Formula==
===General===
Sectional density is stated as:
 
:<math>SD_{Physics} = \frac{M}{A}</math><ref>[http://www.jbmballistics.com/ballistics/topics/secdens.shtml Sectional Density and Ballistic Coefficients]</ref>
* SD = Sectional Density
* '''[[Mass|M]]''' = weight of the object, [[kg]], [[Gram|g]] or [[Pound (mass)|lb]], [[Grain (unit)|gr]]
* A = cross-sectional [[Area of a disk|area]], [[Metre|m<sup>2</sup>]] or [[Inch|in<sup>2</sup>]]
 
===Ballistics===
or for projectiles with a [[Circle|circular]] cross-sectional area like [[bullet]]s or [[Shell (projectile)|shell]]s:
 
:<math>SD_{Ballistics} = \frac{M}{d^2} \approx {p}</math><ref>[http://www.jbmballistics.com/ballistics/topics/secdens.shtml Sectional Density and Ballistic Coefficients]</ref>
* sd is the bullets or shells sectional density
* '''[[Mass|M]]''' is weight of the bullet, [[kg]], [[Gram|g]] or [[Pound (mass)|lb]], [[Grain (unit)|gr]]
* d<sup>2</sup> is the bullet or shell diameter squared, [[Metre|m<sup>2</sup>]] or [[Inch|in<sup>2</sup>]]
* p is [[pressure]]
Units of [[pressure]] are, kg/m<sup>2</sup> or lb/in<sup>2</sup>.<br>
In Europe the derivative unit g/cm<sup>2</sup> is also used in literature regarding [[small arms]] projectiles to get a number in front of the decimal separator.
 
==Use in ballistics==
The sectional density of a projectile can be employed in two area of [[ballistics]]. Within [[external ballistics]], when the sectional density of a projectile is divided by its [[form factor]]{{dn|date=November 2012}} it yields the projectile's [[ballistic coefficient]].<ref>Bryan Litz. Applied Ballistics for Long Range Shooting.</ref>
 
Within [[terminal ballistics]], the sectional density of a projectile is one of the determining factors for projectile penetration. The interaction between projectile (fragments) and target media is however a complex subject. A study regarding hunting bullets shows that besides sectional density several other parameters determine bullet penetration.<ref>[http://www.rathcoombe.net/sci-tech/ballistics/wounding.html Shooting Holes in Wounding Theories: The Mechanics of Terminal Ballistics]</ref><ref>MacPherson D: Bullet Penetration—Modeling the Dynamics and the Incapacitation Resulting From Wound Trauma. Ballistics Publications, El Segundo, CA, 1994.</ref><ref>[http://www.gsgroup.co.za/articlesd.html Sectional Density - A Practical Joke? By Gerard Schultz]</ref>
 
Only if all other factors are equal, the projectile with the greatest amount of sectional density will penetrate the deepest.
