Decent approximations and other time savers
Units and Measurement
Good Enough Numbers
A kilogram is just over 2 pounds.
A meter is a bit more than a yard.
The circumference of a circle is a bit under 6 and a half times its radius.
Measuring Turning Circles
When turning 45 degrees or less, the straight line distance is not much smaller than the actual distance the vehicle or creature would have to travel.
When turning 90 degrees, the distance traveled is basically 50% more than the radius.
Measuring Distances
Generally, waving a measuring tape of about the right distance gets you a pretty good idea of how far something can move or shoot.
Charts
Shooting through Objects
For checking if your character can reasonably be expected to hit an enemy on the other side of something
Calculate the most damage your character could be expected to deal. If you have 2-4 attacks, use the damage for a single crit. If your character has more, or is using sniper a double crit becomes more reasonable. Once you have the most damage, compare the amount of damage required to destroy the object (HP * Toughness) with the Effective Material Damage in the chart below. If the EMD is higher by even a small amount, then it is likely that your character can severely wound if not kill the target.
For checking the results of an attack
Find the EMD for your attack and subtract the effective damage required for the object (HP * Toughness). Then, take the subtracted result and find which EMD values of the matching category that the subtracted result lies between. The lower EMD value indicates the amount of real damage dealt to the target.
