Unit Conversions in Cell Calculations Flashcards

1️⃣ Familiarise yourself with the flashcards:

Look through all the flashcards to see what's on both sides.
Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

Look at the question or prompt on each card and try to remember the answer before flipping it over.
Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What small unit do we often use to measure the length of cells?

We often use micrometres (µm) to measure the length of cells.

There are 1000 micrometres (µm) in 1 millimetre (mm).

There are 1000 nanometres (nm) in 1 micrometre (µm).

You multiply the value in millimetres by 1000. For example, 0.5 mm = 0.5 × 1000 = 500 µm.

You divide the value in micrometres by 1000. For example, 200 µm = 200 ÷ 1000 = 0.2 mm.

You multiply the value in micrometres by 1000. For example, 3 µm = 3 × 1000 = 3000 nm.

You divide the value in nanometres by 1000. For example, 2500 nm = 2500 ÷ 1000 = 2.5 µm.

They must match so the calculation is correct. If the units are different, you must convert them to the same unit first, such as both in µm.

Largest to smallest: millimetre (mm), micrometre (µm), nanometre (nm).
