SI Units worksheet - Free Printable

Let’s go step by step to fill in the missing parts of the SI Units table.

We know that SI units are standard measurements used in science. Each base quantity has a specific base unit and symbol.

Looking at the table:

1. Temperature → Symbol is K → So, what’s the base unit?
→ The base unit for temperature in SI is kelvin.

2. Second (s) → That’s the unit for time → So, what’s the base quantity?
→ The base quantity is Time.

3. Length → Unit is meter → What’s the symbol?
→ The symbol for meter is m.

4. Electrical current → What’s the unit and symbol?
→ Base unit is ampere, symbol is A.

5. Mole (mol) → That’s for amount of substance → So, base quantity is Amount of substance.

6. Luminous Intensity → Unit is candela → What’s the symbol?
→ Symbol is cd.

7. Kilogram (kg) → That’s for mass → So, base quantity is Mass.

Now let’s put it all together in order as shown in the table rows:

Row 1: Temperature → kelvin → K
Row 2: Time → Second → s
Row 3: Length → meter → m
Row 4: Electrical current → ampere → A
Row 5: Amount of substance → mole → mol
Row 6: Luminous Intensity → candela → cd
Row 7: Mass → kilogram → kg

Final Answer:
Base Quantity | Base Unit | Symbol
---|---|---
Temperature | kelvin | K
Time | Second | s
Length | meter | m
Electrical current | ampere | A
Amount of substance | mole | mol
Luminous Intensity | candela | cd
Mass | kilogram | kg
