Convert 7kg to Grams: Basic Metric Unit Conversion

Q: Why do I multiply by 1000 and not divide?

Think about it logically: grams are smaller units than kilograms, so you need more of them to equal the same mass. Since 1 kg = 1000 g, you multiply to get more units!

Q: How can I remember the conversion factor?

Remember "kilo" means 1000! Just like a kilometer is 1000 meters, a kilogram is 1000 grams. The prefix "kilo" always means multiply by 1000.

Q: What if I need to convert grams back to kilograms?

To go the opposite direction (g to kg), you divide by 1000. For example: $ 3500 \text{ g} ÷ 1000 = 3.5 \text{ kg} $

Q: Are there any shortcuts for this conversion?

Yes! Moving from kg to g means moving the decimal point 3 places right: 7.0 kg becomes 7000 g. Add three zeros or move the decimal!

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

Your gram answer should be larger than your kilogram numberDivide your answer by 1000 - you should get back to the original kg amount7000 grams sounds reasonable for 7 kg of mass

$7kg=?gr$

Step-by-step solution

To solve this problem of converting kilograms to grams, we will follow these steps:

Step 1: Identify the given weight in kilograms.
Step 2: Use the conversion factor $1 \text{ kg} = 1000 \text{ g}$ .
Step 3: Perform the necessary multiplication.

Let's go through these steps in detail:
Step 1: We have been given a weight of $7$ kilograms.
Step 2: Recall that $1 \text{ kilogram} = 1000 \text{ grams}$ .
Step 3: Multiply the number of kilograms by the conversion factor: $7 \text{ kg} \times 1000 \text{ g/kg} = 7000 \text{ g}$ This calculation confirms that $7$ kilograms is equivalent to $7000$ grams.

Therefore, the solution to the problem is $7000 \text{ grams}$ .

$7000$

Key Points to Remember

Essential concepts to master this topic

Conversion Rule: One kilogram always equals exactly 1000 grams

Check: Divide answer by 1000 to get back original: 7000 ÷ 1000 = 7 kg ✓

Common Mistakes

Avoid these frequent errors

Dividing by 1000 instead of multiplying
Don't divide 7 by 1000 to get 0.007 grams! This makes the mass smaller when converting to a smaller unit. Always multiply by 1000 when going from kg to grams since there are more grams than kilograms.
