For example a Russian source says a bullet is 7.9mm in diameter, weighs 7.9 grams and flies at 715 m/s with 2019 J of energy... what useless information, now I have to convert it to the ICONIC Imperial system.
In my head I know:
1 inch = 25.4 mm
1 gram = 15.4324 grains
1 meter = 3.280839895012 feet
J = (1/2)m*v^2
So 0.311 diameter, 123.5 grains at 2,345 ft/s...
The energy is (1/2)123.5*2345^2/7000/32.174 = 1508 ft·lb
MUCH SUPERIOR

I'm not talking about converting between both systems, I already know that they are different
For exemple

(and 1 cubic feet its not 7,5 gallons its 7,48051948, this generates a lot of inaccuracy and error)
In metric system
1500 Gallons =~ 5678 Liters
5678 Liters = 5,678 m³ (cubic metres)
0,000000005678 Km³ = 0,000005678 Hm³ = 0,005678 Dm³ = 5,678 m³ = 5678 dm³ = 5678000 cm³ = 5678000000 mm³
(3 by 3 because its cubic)
1 Km = 10 Hm = 100 Dm = 1000 m = 10000 dm = 100000 cm = 1000000 mm
In metric system many of internal convertions are direct, you dont need to make calculations, its much more efficient
