How to Do Conversions

In the next screens, you are asked to convert between SI Units of volume.

To convert from a larger unit to a smaller unit

  1. Find by how many times the larger unit is bigger than the smaller unit
  2. Multiply the larger unit by this number

To convert from a smaller unit to a larger unit

  1. Find by how many times the smaller unit is less than the larger unit
  2. Divide the smaller unit by this number
Example
Convert 45 millilitres to microlitres.

1 ml = 10-3 l
1 µl = 10-6 l

1 ml is 10-3 times ie 103 times larger than 1 µl
10-6
Thus: 45 ml = 45 x 1000 µl = 45000 µl

Example
Convert 565 microlitres to millilitres.

1 ml = 10-3 l
1 µl = 10-6 l

1 µl is 10-3 times ie 103 times smaller than a ml
10-6
Thus: 565 µl = 565 / 1000 ml = 0.565 ml
