1Kg-Wt=10 Newtons
Kg & Newtons r not same units.
The actual equation is given below ...
W=mg
W=weight (S.I. unit : Kg-Wt)
m=mass (S.I. unit : Kg)
g=gravitatinal acceleration (S.I.unit : Newtons)

Doesn't work that way. A newton (N) is a measure of force. A kg (kilogram) is a measure of mass. So your question cannot be answered without more specification.
What I think you meant to ask is:
How many N does a kg weigh at rest on the Earth's surface?
The answer to that is: about 9.8 N = mg = 1 kg X 9.8 m/sec sec; where m is the mass (e.g., 1 kg) and g is the acceleration (g) due to gravity. N is what the mass weighs in Newtons when the mass is in kg and the acceleration is in meters per sec-sec.
At normal non-relativistic velocities, m does not change for a given body. But its weight can, depending on where it is located. The g value in mg varies according to what body is causing the acceleration due to gravity. So g on the Moon is about 1/6 the g on Earth. So that 1 kg of mass would weigh about 1.3 N (= 1/6 X 9.8 N) on the Moon.
Weight is a specific kind of force...force stemming from gravity. But other forces can act on your 1 kg to make it appear to be lighter or heavier. For instance, a tight turn in an aircraft can make the 1 kg appear to weigh a lot more than the 9.8 N we calculated earlier.
For example, we might turn tight enough that your 9.8 N weight appears to be 19.6 N, twice normal weight; in which case we say the mass is "pulling 2 g's," which simply means twice the normal, at rest pull of gravity. That increased weight comes from something called centripetal force, which is due to changing direction.

The question cannot be answered since the two units are measures of different quantities. Newtons measure the force exerted on an object where as kilo grams is the unit of mass of the object which is the property of the object that resists changes in motion. If you are actually asking what is a newton expressed in its base units then it is kilo grams times metres divided by seconds squared o r in symbols N=Kgms^-2. This means that if an object of mass 1Kg is accelerating at 1ms^-2 then it is under a force of 1N provided the objects mass is not changing. The unit of force, the newton, can never be equal to some dimensionless number times the unit of mass, the kilo gram.

Newtons is the unit for force while kg is the unit for mass.
Mass is a constant and is the amount of matter in a substance.
Force (or weight, F = ma) is dependent on the gravitational acceleration present. So on Earth, a 1kg object will have a weight of 1kg x 9.81 m/s2 = 9.81 Newtons (or N).

9.8 newtons=1kg.
(A newton is the amount of force required to accelerate a mass of one kilogram by one metre per second squared.)
Examples:
1 N is the force of Earth's gravity on an apple with a mass of about 102 g.
On Earth's surface, a mass of 1 kg exerts a force of 9.8 N on its support.

9.8 N = 1 Kg (assuming you are talking about on Earth)
all weight exerted is dependant on the mass of the object and the acceleration due to gravity. i.e.
W = mg
in this case, the mass m is 1Kg and the acceleration due to gravity g is 9.8m/s^2 (on Earth. for other planets it would be different). therefore 1Kg mass exerts:-
1 x 9.8 = 9.8 Newtons of force

Newtons don't equal kg. The kg is the SI unit of mass. It is one of the 7 basic SI units from which all other units are derived. The Newton is the SI unit of force. It is a derived unit. Kg and Newtons are related through F= ma where F is is force in Newtons, mass in Kg and a is acceleration in meters per second per second. One Newton is the force required to give a mass of 1 kg an acceleration of 1 ms^-2. Hence 1 N is 1 kg m s^-2.

Most of the answers above are unfortunately wrong.
The kg is the unit of mass, but it also exerts a force of 1kg weight or 9.8 Newtons, when under gravity.

So many Newtons (force) does not 'equal' 1kg (mass).
Your question depends on the rate of acceleration of the mass.
On Earth, where acceleration due to gravity is 9.8m/s/s, the force exerted upon a mass of 1kg is 9.8N (usually rounded up to 10N)

Kg. is mass; Newton is a force. Diffenent quantities.
F=ma
You must multiply mass x acceleration to get Newtons.
