Question

Order these units from smallest to largest:

cm,um,km,mm,m,nm,dm,pm
Give each a measurement in terms of meters.

Answer 1

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

Answer 2

Order from smallest to largest:

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

Step-by-step 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<10^(-6) m<0.001 m< 0.01 m< 0.1 m<1 m<1000 m`

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