The appropriate unit to measure weight is the newton. Now, if it is really the mass you wanted, you could use kilogram or gram.

Standard deviation is a commonly used measure of the variability of a set of measurements.But that usually refers to a 'normal' distribution - an assumption that the results are distributed according to a 'normal' (Gaussian) curve. There are several other types of distribution, Poisson, Bernoulli, and others.It is important to note that the application of standard deviation becomes less and less useful as one approaches the extremes of the set of measurements.
