1 kg is equal to how many grams?

1 kilogram is equal to 1000 grams because the metric system operates on a base-10 system, where each unit is a power of ten. In this system, the prefix "kilo" denotes a factor of 1000. Therefore, when converting kilograms to grams, you multiply the number of kilograms by 1000. In this case, since there is 1 kilogram, it translates directly to 1 x 1000 grams, resulting in 1000 grams. This understanding of the metric system is fundamental in healthcare and various scientific fields, ensuring accurate dosage calculations and conversions.
