Question

Order these units from smallest to largest:

Answer 1

Pm, nm, um, mm, cm, m, dm, km

Answer 2

Answer:

Order from smallest to largest:

: 1 pm < 1 nm < 1 um < 1 mm < 1 cm < 1 dm < 1 m < 1 km.

Explanation:

m = meter

1) cm = centimeter

1 cm = 0.01 m

2) um = micrometer

1 um = $10^{-6} m$

3) km = kilo meter

1 km = 1000 m

4) mm = millimeter

1 mm = 0.001 m

5) m = 1m = meter

6) nm = nano meter

1 nm = $10^{-9} m$

7) dm = decimeter

1 dm = 0.1 m

8) pm = picometer

1 pm = $10^{-12} m$

Order from smallest to largest:

:$10^{-12} m< 10^{-9} m$

: 1 pm < 1 nm < 1 um < 1 mm < 1 cm < 1 dm < 1 m < 1 km.
