Subject: Margin error calculation?

Hi All,
W´ve been making measurements using TPSDig2, by taking pictures of
scorpions samples with millimeter paper on the background.
First using the measure option under the image tools to define a scale
factor by marking two landmarks using two reference points on millimeter
paper whose distance is 20 mm.
Then we proceed to landmark our interested points and calculate the
distance between them by using the pitagoras formula.
Now we need to calculate the margin error on our measurements but we are
confused as to how to establish it.
Basically we think we need to know what how to make a connection (in
terms of measuring error) between the millimeter paper and our
measurements made using the TPS.
Can you please provide some guidance on this matter?
Many thanks,
Matias
