Question

can somebody explain this ? pls
RELATIONSHIP BETWEEN S.I UNIT AND C. G. S. UNIT OF DENSITY. .
1 Kg is 1000 gm
or 1gm is (below formula )
$\frac{1}{1000| }$
and 1m^3 is ( 100 cm^3)
=100×100×100cm^3
=10,00,000
or 1 cm^3=1 / 10,00,000cm^3

Now 1gm cm^3 is 1g/1 cm
=1/1000 kg
-----------
1/1000000 m^3

=1000000/1000 kg /m^3

=1.000 kg/m^3
Thus,1g cm/m^3=1000kg/m^3

pls army !
pls blink !

I want army energy & blink attitude !

Answer 1

Answer:

The S.I. unit of mass is kilogram (symbol kg) and of volume is

cubic metre (symbol m3). Therefore S.I. unit of density is kg/m3

or kg m-3.

The C.G.S. unit of mass is gram (symbol g) and of volume is cubic centimetre (symbol cm3). Therefore the C.G.S. unit of

density is g/cm3 or g cm-3.

Relationship between kg m-3 and g cm-3

1 kg = 1000 g

or 1 g = (1/1000) kg

and 1 m3 = (100 cm)3

= 100 × 100 × 100 cm3

= 10,00,000 cm3

Or 1 cm3 = (1/1000000) m3

Now 1 g cm-3 = 1g/1cm3



Thus, 1 g cm-3 = 1,000 kg m-3

Answer 2

CGS unit

CGS units are the standard for the metric system; C entimetres, G rams, S econds.

SI unit

(Units) any of the units adopted for international use under the Système International d'Unités, now employed for all scientific and most technical purposes. There are seven fundamental units: the metre, kilogram, second, ampere, kelvin, candela, and mole; and two supplementary units: the radian and the steradian. All other units are derived by multiplication or division of these units without the use of numerical factors.

The seven base quantities and their corresponding units are:

length (metre)

mass (kilogram)

time (second)

electric current (ampere)

thermodynamic temperature (kelvin)

amount of substance (mole)

luminous intensity (candela)

These base quantities are assumed to be independent of one another. In other words, no base quantity needs to be defined in terms of any other base quantity (or quantities).

Relationship

S.I. UNIT OF DENSITY =kg/per cubic metre

CGSUNIT OF DENSITY=g/per cubic centi metre

1kg m per cubic =1kg/1mcube =10000g/(100cm)per cubic

=1/1000 g cm per minus cube

Thus, 1kg m per cubic=10 per cube
