Easily convert your baby’s weight from kilograms to pounds with our simple calculator.
Baby Weight Converter for Moms
As a new mom, you’ll notice that some baby books, doctors, or online groups use kilograms (kg) while others use pounds (lbs). It can get a little confusing, especially when you’re tracking your baby’s growth and want to compare it to different charts or advice from moms around the world.
That’s why I put together this simple guide (and calculator!) to help you quickly convert kilograms to pounds.
Quick Conversion
The basic rule is:
1 kilogram (kg) = 2.20462 pounds (lbs)
Here’s a quick table with some common baby weights:

| 3 kg | 6.6 lbs |

How to Do the Math Yourself
If you don’t have a calculator handy, here’s the formula:
Weight in pounds = Weight in kg × 2.20462
Example: If your baby weighs 3.2 kg:
3.2 × 2.20462 = 7.05 lbs
Why Baby Weight Is Different Around the World
Most countries use the metric system, which includes kilograms. But if you’re chatting with moms in the United States, you’ll hear baby weights in pounds and ounces. That’s why it’s so helpful to know the conversion—it makes sharing and comparing growth milestones so much easier.
Baby Growth & Weight Checks
Here are some general guidelines (remember, every baby grows at their own pace):
- Average newborn birth weight: 2.5–4.5 kg (5.5–10 lbs)
- Most babies regain their birth weight by 2 weeks old
- Babies usually double their birth weight by 5 months
- By 12 months, many babies triple their birth weight
Don’t worry if your little one doesn’t fit these exact numbers—what matters most is that your baby is growing steadily along their own curve.
