Would it be earth?

Mass is a property of matter.
Weight is the force exerted on a mass due to a specific acceleration.
F=Ma
Under earth's gravity the gravitation constant G takes the place of a in F=Ma and a pound mass = a pound force.
G varies slightly by location on the earth's surface {It's slightly different if you are close to the Himalayas than if you are in Kentucky} so the constant G is an average, it's not really a constant.
In SI, a gram is a mass, not a weight. Even though folks talk of their weight in KG, that is not technically appropriate. Newtons is what weight (the force of gravity on their mass) they should be quoting.

Nowhere unless the mass is zero. Otherwise you have a number for the mass with the weight ( force) being determined by mass X acceleration.
More directly, since mass and weight are different things entirely they will never be the same

There are two possible answers:
1)Anywhere that has a gravitational force of 1N/kg, so anywhere that has less gravity than earth since earth is 9.81N/kg
2)Anywhere that has 0 gravity, would give a mass and weight of 0. This would be in the exact centre of the earth or any other planet.

On the planet earth or under any condtion where the gravity is one G.
