Depending where?
In general weight w is a force and as such it is a product of mass m and acceleration due to gravity g.

w=mg

On Earth g= 9.81m/s^2

w=2 x 9.81=19.62 N or since you have measured your mass to 1 significant figure
w= 20 N

Weight = mass X gravity acceleration
Weight = 2 X 9.8
Weight = 19.6 N â 20N

As you take your answer the least significant figure .
