This question cannot be answered. A kilogram is a unit of mass, not distance and so cannot be used to measure a diameter. Mars has a mean diameter of about 6780 kilometers and a mass of 6.4*10^23 kilograms.
Mars' diameter is about 6800 kilometers, and the Earth's diameter is 12,756 kilometers. Comparing the two planets, Mars' diameter is approximately 53 percent that of the Earth's.

Mars has a diameter about 0.53 of the Earth's. Mars has a mass about 0.107 times the Earth's.
Mars is 6,786 Km. in diameter. Big is a relative term. It is big compared to its moons but small compared to the sun
it is not mars is 6794.4 km in diameter where as earth is 12,756.28 km nearly twice as big
Deimos is 12km in diameter
In diameter it is 49,000 kilometers and in mass it is 102,000,000,000,000,000,000,000,000, kilograms.
The radius of Mars is 3397 kilometers. The circumference of Mars at the equator is about 21,343 kilometers.
Mars' diameter is about half that of the Earth and it's mass is only 10% of the Earth's.The total surface area of Mars is about the same as the total land area of the Earth.
Size can mean different things.Mars is just over half the diameter of Earth, and has only 11% as much mass.These are the most common "size" ratios (mars/earth):Mass: 0.107 (10.7%)Mars has 11% of the mass of Earth.Volume: 0.151 (15.1%)Mars has 15% of the volume of Earth.Mean Radius: 0.532 (53.2%)Mars has a radius about half the radius of Earth.The equatorial diameter of Mars is 6792 km (4220 miles).The equatorial diameter of Earth is 12756 km (7926 miles).
First of all, Mars does NOT have an apostrophe. Second of all, the diameter of Mars is 6794 km from the core to the surface.
