Convert 3850ml to Cubic Decimeters (dm³): Unit Conversion Guide

Q: Why do I divide by 1000 instead of multiply?

Think of it this way: smaller units have bigger numbers! Since milliliters are smaller than cubic decimeters, you need more milliliters to equal the same volume. So when converting to the larger unit, you divide.

Q: How do I remember the conversion factor?

Remember that 1 liter = 1000 ml and 1 liter = 1 dm³. So 1000 ml = 1 dm³! This makes the conversion easy to remember.

Q: What if I get a decimal answer?

Decimal answers are perfectly normal for unit conversions! $ 3.85 \, \text{dm}^3 $ means you have 3 full cubic decimeters plus 0.85 of another one.

Q: Can I convert using other methods?

You could use proportions: 3850 ml ÷ x dm³ = 1000 ml ÷ 1 dm³. Cross multiply to get the same answer, but division is faster!

Q: How do I check if my answer makes sense?

Ask yourself: Should the number get bigger or smaller? Since dm³ are larger units than ml, your answer should be a smaller number than 3850. ✓

Understand the problem

Convert $3850ml$ into cubic decimeters.

Step-by-step solution

To solve this problem, we'll follow these steps:

Step 1: Identify the given amount in milliliters which is $3850 \, \text{ml}$ .
Step 2: Use the conversion factor $1 \, \text{dm}^3 = 1000 \, \text{ml}$ .
Step 3: Divide the milliliters by 1000 to convert to cubic decimeters.

Now, let's work through each step:
Step 1: We have $3850 \, \text{ml}$ .
Step 2: We need to convert this volume to cubic decimeters using the conversion factor where $1000 \, \text{ml} = 1 \, \text{dm}^3$ .
Step 3: Perform the conversion by dividing the milliliters by the conversion factor:

$\frac{3850 \, \text{ml}}{1000 \, \text{ml/dm}^3} = 3.85 \, \text{dm}^3$

Therefore, the solution to the problem is $3.85 \, \text{dm}^3$ .

Final Answer

$3.85dm^3$

Key Points to Remember

Essential concepts to master this topic

Conversion Rule: 1 cubic decimeter equals exactly 1000 milliliters
Division Method: Divide 3850 ÷ 1000 = 3.85 dm³
Check Units: Final answer has dm³ units, original had ml ✓

Common Mistakes

Avoid these frequent errors

Multiplying by 1000 instead of dividing
Don't multiply 3850 × 1000 = 3,850,000 dm³! This makes the volume impossibly huge because you're going the wrong direction. Always divide by 1000 when converting from smaller units (ml) to larger units (dm³).
