Metric mixed units

key notes :

🔹 What Are Metric Mixed Units?

Metric mixed units are measurements written using more than one metric unit for the same quantity.
✅ Example: 1 m 25 cm, 3 kg 450 g, 2 L 300 mL

📏 2. Metric Units Used in Mixed Measurements

Quantity	Main Units	Smaller Units
Length ✨	km, m	cm, mm
Mass ⚖️	kg	g
Capacity 💧	L	mL

🔁 Conversion Rules (Important!)

📍 Length

• 1 m = 100 cm
• 1 cm = 10 mm
• 1 km = 1000 m

⚖️ Mass

• 1 kg = 1000 g

💧 Capacity

• 1 L = 1000 mL

🔸 Why Use Mixed Units?

Mixed units help in showing precise measurements clearly.
💡 Example: Instead of 125 cm, we say 1 m 25 cm for clarity.

🔄 Changing Mixed Units to Single Units

👉 Add after converting to the same unit
Example:
2 m 30 cm = 2 m + 0.30 m = 2.30 m
OR
2 m 30 cm = 200 cm + 30 cm = 230 cm

---

➗ Changing Single Units to Mixed Units

Split the units into bigger and smaller units.
Example:
1450 g = 1 kg 450 g
2500 mL = 2 L 500 mL

---

🧠 Quick Tip to Remember

✨ “Break or Join” Rule:
✔️ Join units → convert to same unit then add
✔️ Break units → divide into big + small unit

🧪 Examples

Mixed Unit	As Single Unit
3 m 75 cm	375 cm
4 kg 200 g	4200 g
1 L 650 mL	1650 mL
