Make units do the checking

Tight crop of a lab notebook showing the value “250 µL” inside one solid outlined box, with the number and unit visually attached; beside it, a crossed-out version shows “250” with a loose “µL later” label and a small red “1000×?” warning.

Units are part of the value

In bioengineering, a tiny unit mistake can mean adding 1000 times too much or too little. So do not treat units as labels you add at the end; carry them through the math like part of the number.
