Question

Arrange these units from smallest to largest: cm,um,km,mm,m,nm,dm,pm.

Then give each a measurement in terms of meters.

Answer 1

Arranging units from smallest to largest:
pm, nm, um, mm, cm, dm, m, km.

Individual measurements in terms of 1 meter.
1 x 10^12 pm = 1 m
1 x 10^9 nm = 1m
1 x 10^6 um = 1m
1 x 10^3 mm = 1m
1 x 10^2 cm = 1m
1 x 10^1 dm = 1m
1m = 1m
1 x 10^-3 km = 1m
