Mass and weight are not the same on Earth. Mass can be thought of as a quantity of material substance, whereas weight refers to the force of gravity acting on that mass.
Using the basic relationship
F
=
m
a
, the force of gravity,
F
G
is equal to
m
g
, where
m
is the object's mass and
g
is the acceleration due to gravity, a constant equal to
9.8
m
s
2
.
For example, if an object had a mass of 70kg, it would have a weight equal to
F
G
, where
70
k
g
⋅
9.8
m
s
2
=
686
N
This is approximately 154 pounds.
Note: This value applies on Earth, where
g
=
9.8
m
s

. The value of "g" on other planets or at different (significant) distances from the earth will vary.
An object's mass (in general) is constant, whereas its weight can fluctuate depending on the gravity it is experiencing. You would have the same mass on the moon, for example, but you would weigh less, because gravity on the moon is approximately 1/6 that on Earth.
