1kg( 1 kg) = 2kg =1000g. 1 kg = 500g.

Kilogram is an international unit of mass. Jin is the unit of quality in our country. The conversion relationship is 1 kg =2 kg.

1 kg will be defined as "the mass unit corresponding to Planck constant of 6.62607015×10-34j s". Its principle is to convert the mechanical force required to move the mass 1 kg object into the electromagnetic force that can be expressed by Planck constant, and then calculate the mass through the mass-energy conversion formula.

Extended data:

The kilogram is also one of the most commonly used basic units in daily life. One kilogram is defined as the mass unit when Planck's constant is 6.62607015×10J s, which is almost as heavy as one liter of water. Kilogram is the only basic unit with the prefix of international system of units.

On 20 18 1 1 month 16, the 26th international metrology conference adopted the resolution of "revising the international system of units", which formally updated the definition of "kilogram" including the international standard quality unit. The new system of international units came into effect on May 20th, 20 19, World Metrology Day.

Kilogram is a metric unit of measurement, and one kilogram is equal to one kilogram, which is equivalent to two kilograms in China.
