Metric mixed units

Key Notes :

🎯 1. Understanding Metric Units

The metric system is based on powers of 10, making it easy to convert between units by multiplying or dividing.

• Length: millimeters (mm), centimeters (cm), meters (m), kilometers (km)
• Mass: milligrams (mg), grams (g), kilograms (kg)
• Volume: milliliters (mL), liters (L)

---

🔄 2. Conversion Basics

• To convert to a smaller unit → Multiply
• To convert to a larger unit → Divide

Example:

• 1 meter = 100 centimeters → Multiply by 100 to convert meters to centimeters.
• 1000 grams = 1 kilogram → Divide by 1000 to convert grams to kilograms.

📏 3. Length Conversion Table

Unit	Relationship
1 kilometer (km)	1000 meters (m)
1 meter (m)	100 centimeters (cm)
1 centimeter (cm)	10 millimeters (mm)

Example:

• Convert 4 kilometers to meters:
  4×1000=4000 m

---

⚖️ 4. Mass Conversion Table

Unit	Relationship
1 kilogram (kg)	1000 grams (g)
1 gram (g)	1000 milligrams (mg)

Example:

• Convert 750 grams to kilograms:
  750÷1000=0.75 kg

---

💧 5. Volume Conversion Table

Unit	Relationship
1 liter (L)	1000 milliliters (mL)

Example:

• Convert 2.5 liters to milliliters:
  2.5×1000=2500 mL

---

🔍 6. Comparing Metric Units

When comparing metric units:

• Larger units → for bigger measurements (e.g., kilometers for distances between cities)
• Smaller units → for tiny measurements (e.g., millimeters for small objects)

Example:

• Which is larger: 3 meters or 250 centimeters?
  Convert 3 meters to centimeters:
  3×100=300 cm → 3 meters is larger

📝 7. Quick Tips for Converting and Comparing

• Remember the patterns: Kilo → Hecto → Deca → Base Unit → Deci → Centi → Milli
• Multiply for smaller units, divide for larger units
• Check your units to ensure answers make sense (e.g., a pen should weigh grams, not kilograms!)
