One kilogram (1 kg) is equivalent to 1000 grams (1000 gm). To convert from kilograms to grams, you can use the conversion factor of 0.001. In this case, the ‘m’ in ‘gm’ stands for mass, which means that the mass in kilograms (kg) can be converted to grams (gm) by multiplying it by 1000. Therefore, 1 kg is equal to 1 x 0.001, which equals 1000 grams.
