I'm going to take a picture of a bacteria but I am unsure how large it is. What are the dimensions in angstrom of bacteria?

  • $\begingroup$ if you know in microns then you can convert it into angstrom. But why angstrom. It is a very small unit for cellular dimension $\endgroup$ – WYSIWYG Aug 16 '14 at 7:36

    $\begingroup$ Usually you know the scale of the micrograph and measure the size of the object in it to get its size, not the other way round ;) $\endgroup$ – shigeta Aug 18 '14 at 5:58

According to Wikipedia: 3 um long with a diameter of 0.5 um. That equates to a length of 30 000 A and a diameter of 5 000 A.
