![Often pipettes need to be tested for accuracy
You would use a digital balance you to determine how accurate your pipet is and how
accurate you are at pipetting. The rule of thumb is that 1 g =1 ml. If you pipet 540 ul of water
onto a digital scale it should measure 0.54 g because 1 ml = 1,000 ul; therefore 540 ul =
0.54 ml = 0.54 g.
