Returns JOULE value, knowing a bullet weight (exp. in grams or grains) and its speed (expressed in meters per second m/s or feet per second ft/s).
Knowing the JOULE value of a weapon and the weight of the bullet, it determines the own speed in m/s. or ft/s , as well the weight (exp. in grams or grains) if you input its speed.
Options added :
mt/sec (metri al secondo) > gram
ft/sec (feet per second) > gram
mt/sec (metri al secondo) > grain
ft/sec (feet per second) > gram
All these options are now defined by a new dedicated page.
All reverse calculations are performed.
It is also possible to input from 1 to 4 different speed of bullets, and obtain an averaged JOULE value.
You can now use dot or comma to define decimals input.
Speeds and weights units are now defined by a picker.
