So, 140 lbs is approximately 63.5 kg.
Why Convert Pounds to Kilograms?
You might be asking, “Why do I even need to know this?” Well, there are a few good reasons!
- Global Standards: Most countries, particularly those in Europe, use kilograms for weight measurements. If you’re traveling or buying products internationally, you’ll often see weight measured in kilograms.
- Health and Fitness: If you’re tracking your fitness goals, weight loss, or body mass index (BMI), you might come across numbers in kilograms, especially on health websites or when discussing your weight with a healthcare professional.
- International Recipes: Sometimes when you’re cooking, especially if you’re following international recipes, you’ll encounter measurements in kilograms instead of pounds. Knowing how to convert can save you a lot of guesswork.
