# Cells - Cell structure - 3.2.1.6 - Cell Calculations and AIM Triangle Flashcards

Identify what is missing from the unit conversion diagram.

How do we calculate the miagnificaiton of an image?

Magnification = Image Size ÷ Actual Size

1 m in µm =

1 x 10^{6} µm

What can we use to help rearrange the equations for calculating image size, actual size and magnificaiton?

Identify what is missing from the unit conversion diagram.

How should you calculate magnificaiton if there is a ‘scale bar’ present on a photomicrograph?

You are given the Actual Size next to the scale bar

Measure the Image Size using a ruler

Magnificaiton = Image Size ÷ Actual Size

1 nm in m =

1 x 10^{-9} m

1 m in nm =

1 x 10^{9} nm

Identify what is missing from the unit conversion diagram.

1 µm in m =

1 x 10^{-6} m

Identify what is missing from the unit conversion diagram.

1 mm in m =

1 x 10^{-3} m

How can we calculate the size of the ** image** being observed through microscope?

Image Size = Actual Size x Magnification

When doing cell calculation you should make sure that you are working in which units?

Micrometres
