milli- prefix means: x 10-3
centi- prefix means: x 10-2
volume = mass ÷ density
area = length x width
1 ft = 30.48 cm (exactly)
thickness = volume ÷ area
= (200 mg ÷ 19.32 g/cm3) ÷ (2.4 ft x 10 ft)
= (200 x 10-3 g ÷ 19.32 g/cm3) ÷ ((2.4 x 30.48) cm x (10 x 30.48) cm)
≈ 0.000000464 cm
= (4.64 x 10-7) x (10-2) m
= 4.64 x 10-9 m
= 4.64 nm
(The nano- prefix means: x 10-9.)

The thickness is of the order of a millimetre so a smaller unit - a micrometre, perhaps - is suitable.

An ultrasonic thickness gauge is required for measuring the thickness of different types of materials. The best ultrasonic thickness gauge you can buy is the Defelsko Corporation Ultrasonic Thickness gauge.
