Metric Conversion Worksheet | Download Free PDF | Metre | Quantity - Free Printable

Let’s solve each problem one by one. We’ll use the metric prefix chart at the bottom to help us. Remember:

- To convert DOWN (to smaller units), move decimal RIGHT.
- To convert UP (to larger units), move decimal LEFT.

The prefixes in order from largest to smallest:
Kilo (1000) → Hecto (100) → Deca (10) → BASE (1) → Deci (1/10) → Centi (1/100) → Milli (1/1000)

1. 5 meters = ______ km

Meters to kilometers → going UP 3 steps (m → deca → hecto → kilo)
Move decimal LEFT 3 places:
5.0 → 0.005
✔ 0.005 km

---

2. 3 grams = ______ milligrams

Grams to milligrams → going DOWN 3 steps (g → deci → centi → milli)
Move decimal RIGHT 3 places:
3.0 → 3000
✔ 3000 mg

---

3. 7 meters = ______ cm

Meters to centimeters → going DOWN 2 steps (m → deci → centi)
Move decimal RIGHT 2 places:
7.0 → 700
✔ 700 cm

4. 60 milligrams = ______ km

Milligrams to kilometers? That’s a huge jump! Let’s go step by step.

First, convert mg to grams:
mg → g is UP 3 steps → move decimal LEFT 3:
60 mg = 0.060 g

Now, grams to kilograms:
g → kg is UP 3 more steps → move decimal LEFT 3 again:
0.060 g = 0.000060 kg

But we need kilometers, not kilograms — wait! This is a trick question. Milligrams are mass, kilometers are distance. You can’t convert between them!

Wait — maybe it’s a typo? But since the worksheet says “convert”, and assuming they meant millimeters to kilometers? Or perhaps it’s testing if you notice?

Actually, looking back — no, the unit is “milligrams” to “km”. That doesn’t make sense physically. But maybe in this context, they just want the numerical conversion as if it were length? That would be wrong scientifically, but let’s assume they meant millimeters to kilometers for consistency with other problems.

Alternatively — perhaps it’s a mistake and should be millimeters? Let me check problem 10: “44 millimeters = ___ m” — so yes, likely a typo here.

But since the problem says “60 milligrams = ___ km”, and that’s impossible, I think we have to assume it’s a typo and they meant millimeters.

So let’s do: 60 millimeters = ______ km

mm → km: going UP 6 steps (mm → cm → dm → m → dam → hm → km)
Move decimal LEFT 6 places:
60.0 → 0.000060
✔ 0.00006 km

*(Note: If strictly following the text, this conversion is invalid — but for worksheet purposes, we’ll proceed as if it’s mm to km.)*

5. 2.5 meters = ______ mm

Meters to millimeters → DOWN 3 steps (m → dm → cm → mm)

6. 4.5 centimeters = ______ km

Centimeters to kilometers → UP 5 steps (cm → dm → m → dam → hm → km)

4.5 → 0.000045
✔ 0.000045 km

Move decimal RIGHT 1 place:
77.0 → 770
✔ 770 dm

---

8. 37 decimeters = ______ mm

Decimeters to millimeters → DOWN 2 steps (dm → cm → mm)

0.002 → 0.02
✔ 0.02 mm

---

10. 44 millimeters = ______ m

Millimeters to meters → UP 3 steps (mm → cm → dm → m)
Move decimal LEFT 3 places:
44.0 → 0.044
✔ 0.044 m

---

11. 25 kilometers = ______ m

Kilometers to meters → DOWN 3 steps (km → hm → dam → m)
Move decimal RIGHT 3 places:
25.0 → 25000
✔ 25000 m

---

12. 880 meters = ______ cm

Meters to centimeters → DOWN 2 steps (m → dm → cm)

880.0 → 88000
✔ 88000 cm

---

13. 9.5 kiloliters = ______ deciliters

Kiloliters to deciliters → DOWN 4 steps (kL → hL → daL → L → dL)
Move decimal RIGHT 4 places:
9.5 → 95000
✔ 95000 dL

---

14. 66 decimeters = ______ decameters
