Anickel is about 2 millimeters thick, or 2/1,000 of a meter how many nanometers is this

This is a unit conversion problem. Nm (nanometer) is smaller than mm (millimeter).

1 mm = 1/10³m = 1 x 10⁻³ m

1 nm = 1/10⁹ m = 1 x10⁻⁹ m

1 m = 1 x 10⁹ nm

Hence, 2 mm = 2 x 10⁻³ m

Then we can convert 2 x 10⁻³ m to nm by multiplying with 10⁹.

Then 2 mm = 2 x 10⁻³ m = 2 x 10⁻³ x 10⁹ nm = 2 x 10⁶ nm.

Hence, the thickness of nickel is 2 x 10⁶ nm.

have a great day because if you dont you and i will be sad
