a)5〖m.〗^2 a 〖cm.〗^2 b) 1pg. a cm.

1m^2=10000〖cm〗^2 1pg. =0.254m.=2.54cm.

5m^2=? =2.54cm.

(5m^2 (10000〖cm〗^2))/ 1m^2=50000〖cm〗^2/1

=50000〖cm〗^2

c) 1〖pg.〗^2 a 〖cm.〗^2 d) 1〖m.〗^3 a lts.

1pg. =2.54cm. 1 lts.=1d〖m.〗^3

1〖pg〗^2 = (2.54〖cm.)〗^2 1m^3 =1000 lts.

1〖pg〗^2 =6.452 〖cm.〗^2 =1000 lts.

e) 1〖m.〗^3 a 〖cm.〗^3 f) 1lb/〖pg.〗^2 a kg./〖cm.〗^2

1m.^3=1000〖dm.〗^3 1lb=453.59g ,

=1000000m.^3 1〖pg〗^2 =6.452 〖cm.〗^2

1kg. =1000g.

? kg.= 453.59g

(453.59g(1kg.))/ 1000g. =0.4535kg.

1lb/〖pg.〗^2 =0.4535kg./ 6.452〖cm.〗^2

=0.069 kg./〖cm.〗^2

g) 1c.c a ml. h) 1N. a kg.

〖 1cm.〗^3=0.00000〖1m.〗^3 1kg.= 9.81N.

=1 ml. ? kg. =1N.

(1n(1kg.))/ 9.81N. =0.10kg.

I) 1N a Dinas.

1N =1 kg.m./〖s.〗^2

=〖10〗^5 g.cm./〖s.〗^2

=〖10〗^5 dyn.
