how many e. coli could you line up, end to end, in one mm, assuming the E. Coli is 2 micrometers long?

1,000 micrometers = 1 mm

Thank you Ms. Sue!

You're welcome, Michael.

To find out how many E. coli can be lined up end to end in one millimeter, we need to convert the length of the E. coli from micrometers to millimeters and then perform a simple division.

1 micrometer (μm) = 0.001 millimeters (mm)

Given that the length of an E. coli is 2 micrometers, we can convert it to millimeters:

2 micrometers = 2 x 0.001 = 0.002 millimeters

Now, to calculate the number of E. coli that can fit in one millimeter, we use the formula:

Number of E. coli = Length of space / Length of each E. coli

Number of E. coli = 1 mm / 0.002 mm

Number of E. coli = 500

Therefore, you could line up approximately 500 E. coli end to end in one millimeter.
