Here are the conversions:

27°C to Kelvins:

𝐾

=

°

𝐶

273.15

K=°C+273.15

So,

27

°

𝐶

=

27

273.15

=

300.15

K

27°C=27+273.15=300.15K

20 dg to milligrams: 1 decigram (dg) = 100 milligrams (mg), so:

20

dg

=

20

×

100

=

2000

mg

20dg=20×100=2000mg

3 meters to decimeters: 1 meter (m) = 10 decimeters (dm), so:

3

m

=

3

×

10

=

30

dm

3m=3×10=30dm

So the answers are:

300.15 K for 27°C,

2000 mg for 20 dg,

30 dm for 3 meters.
