• 1 kilogram is =to 2.2 pounds!?
• to convert kg to pound for an approximate result, multiply the mass value by 2.20462262
The answer is 1 kg= 2.2046Pounds
• What's the easiest way to remember how to convert between grams and kilograms?
• Since kilo in the word kilograms means 1000, there are 1000 grams in a kilogram. You will also learn about miligrams, which is 1000 times less than a gram because milli means 1000 times less.
• kilograms our 1000 grams so i am a kid so dont bully am right
• Weight of 6 cows is 50.08 kilograms.what will be weight of 3 cows in grams
• There are 2 groups of 3 cows in 1 group of 6 cows, so all there is to do is 50.08/2! 5/2 = 2 with a 1 left over. 10/2 = 5. 0/2 = 0. 8/2 = 4. So your answer is 25.04 kilograms, but you asked for the answer in grams. There are 1,000 grams in a kilogram, so all we need to do now is 1,000 x 25.04! 1,000 x 25.04 = 250,400! The answer is 250,400 grams! I hope this helps!
• when your doing weight and measurement I know that multiplication comes in to the picture but does subtraction and/or addition being used as well?
• it is used, but not commonly.
• 700kg for a cow 1500.
