Please anybody tell me the formula of weight measuring of the offset plate.

To get the area of one plate, simply multiple the width x length of the plate. Multiple your per-m2 price by that result, and you'll have the price per plate.
Example: plate size is 605x745mm (i.e. 0.605 x 0.745 meters), area is 0.605x0.745 = 0.451 m2.
$3 x 0.451 = $1.35 per plate.
Weight is just a bit more difficult. Note that the thickness (gauge) noted on the box of the plate isn't an exact measurement. The actual thickness is likely a little thinner - due both to the metal being thinner to begin with, and that some of the metal is removed in the graining process. Typically 0.15mm plates are about 0.14mm, 0.3mm plates are about 0.275mm, and 0.4mm plates are about 0.38mm.
For 0.3mm plates, an approximate value is 750g per m2. If you need exact, multiply the plate area (as above) by the thickness (above), by the density of aluminum - which is 2.7g per cm3. You'll have to ensure you're using consistent units of course... multiple/divide by 1000 as needed.

The formula you wrote is correct, but I get $0.987/plate when I do that exact same calculation though.
51.0 x 64.5 * 0.014 = 46.05 cm3 of aluminum (all units here are converted to cm)
46.05cm3 * 2.7g/cm3 = 124.3g per plate
This assumes that your plate is "0.15mm" thickness (0.14mm in reality though).
Kevin.
Yes, that looks correct to me. Good luck!
out of curiosity - what are you using/needing this for? Scrap metal value calculations?
