A piece of almunium foil is 8.0x10cm thick what is thickness in micrometrs

Question

10^-5

Answer 1

Not sure what the numbers are in your question, but I'm going with a thickness of 8.0x10^-5 cm, and will convert that to microns/micrometers (u)

1 u (microns) = 10^-6 m

1 cm = 10^-2 m

Thus, 1 u = 10^-4 cm

8.0x10^-5 cm x 1 u / 10^-4 cm = 0.80 u (microns or micrometers)
