Frequently Asked Questions
Frequently Asked Questions
How accurate are the weight conversions?
Our weight converter uses internationally recognized conversion factors and provides results accurate to 6 decimal places. The conversions are based on official standards from organizations like NIST (National Institute of Standards and Technology) and are suitable for both everyday use and professional applications.
What's the difference between weight and mass?
In everyday language, "weight" and "mass" are often used interchangeably, but technically they're different. Mass is the amount of matter in an object (measured in kg, g, etc.), while weight is the force exerted by gravity on that mass (measured in newtons). For practical purposes, our converter handles both using the same units.
Can I convert between metric and imperial units?
Yes! Our converter supports conversions between all major metric and imperial units. You can convert from kilograms to pounds, grams to ounces, metric tons to US tons, and any other combination of supported units. The converter automatically handles the conversion factors between different systems.
What units are best for cooking?
For cooking, grams and ounces are most precise for dry ingredients, while milliliters and fluid ounces work well for liquids. Our converter helps you switch between metric (grams) and imperial (ounces) measurements, which is especially useful when following international recipes or using kitchen scales with different unit displays.
How do I convert body weight between kg and lbs?
Simply enter your weight in kilograms and select "lbs" as the target unit, or vice versa. For example, 70 kg = 154.32 lbs. This is useful for fitness tracking apps, medical records, or when traveling between countries that use different measurement systems.
What are carats and grains used for?
Carats are primarily used for measuring gemstones and pearls (1 carat = 0.2 grams). Grains are used in ammunition (bullet weights) and precious metals. These specialized units are included in our converter for professionals in jewelry, firearms, and precious metals industries.
