The mass of Mars is approximately equal to 6.4191 × 1023 kilograms. It has a radius of 3397 kilometers and its equatorial circumference is 21,344 kilometers (or 13,263 miles).

In comparison…

The earth's mass is approximately equal to 5.9742 × 1024 kilograms. It has a radius of 6,378 kilometers and its equatorial circumference is 40,075 kilometers (or 24,902 miles).

Remember, planetary mass changes every day due to the fact that falling matter from space is perpetually raining down. It is estimated that earth alone gains 10^8 kilograms every day from this "star dust" that finds its way here.
