The first definition of the kilogram was the weight of one liter of water. Which is already better than "the weight of stone" but still has problems. Some of them are due to the fact that the density of water changes with temperature and pressure, making it necessary to set some common...
A kilogram (Kilo or Kg) is, simply put, 1,000 grams, or the weight of one liter of water. The accepted mass of a kilogram today is within 30 parts per million of the definition from 1795, showing little change over the past 227 years. How many Grams in a Kilo- Gram to Kilogram ...
For example:let’s find the weight of 250 mL of water. Step one: convert volume to liters: Volume (L) = 250 mL ÷ 1000 = 0.25 L Step two: using the density of 1 kg/L, calculate the weight of 0.25 L of water: Weight (g) = 0.25 L × 1 kg/L = 0.25 kg = 250 g ...
for example, your mass would be the same as it is on the Earth, but your weight would be one sixth of what it is on the Earth because of the lower gravitational pull of the moon. If this is so, you might ask, how can my science teacher ask me to convert pounds into kilograms?
The molecular weight of water is the combined weight of its two hydrogen atoms and one oxygen atom which amounts to 18.015 atomic mass units. The unit weight of water or specific weight of water is the same as the weight of one gallon of water. Of course, you could use any unit size...
In the higher age group of 10 to 12, 27% of those who had a dog were over-weight, and 30% of those who didn’t have a pet dog were over-weight.“Even playing incidentally(偶然地) with a dog helps a child lose weight,” said Professor Salmon, one of the researchers. “We all ...
The density of liquid water is 1 g/mL, meaning in every milliliter of water there is 1 gram of water. Answer and Explanation: The mass of 1 L of water is 1000g and the weight in Newtons is 10 N. To find the mass of the water, we must first convert the liters (...
The human body is 60% water by weight. How much water in liters does a 196 lb man contain? Conversion of Units Conversion of units is important in measurements. In order to correctly convert the unit, one must know the ratio of the units you want to conv...

A gram is a unit of mass equal to 1/1,000 of a kilogram or 0.035274 ounces, and is equivalent to the mass of one cubic centimeter, or one milliliter, of water. How to Convert Grams To convert grams to another unit of weight, you need to multiply the value by a conversion factor...
