Final Answer:
The two things that must be recorded in all measurements are:
1. The numerical value (e.g., 5.2)
2. The unit (e.g., cm, mL, g)

Explanation:
When you measure something—like length, volume, or mass—you always need two parts to make your answer complete and meaningful:

1. A number (how much?)
2. A unit (what kind of measurement? cm? mL? grams?)

For example:
- Saying “5” alone doesn’t tell us anything—it could be 5 cm, 5 mL, or 5 kg.
- But saying “5.2 cm” tells us exactly what was measured and how big it is.

In science, if you forget the unit, your measurement is useless—even if the number is correct.

That’s why every time you write a measurement, always include both the number *and* the unit.
