Anyone who knows why the SI-unit for mass is chosen to kg and not g?
I think I know why they have chosen the kms system...this just sounds like you had a fishbone in your throat :yuck:HallsofIvy said:erg
The SI-unit for mass, or kilogram (kg), was chosen because it is a more practical and convenient unit for everyday use. It is larger than the gram (g) and allows for easier measurement of larger objects without using decimals.
While grams (g) are commonly used for measuring small masses, using kilogram (kg) as the SI-unit for mass allows for a more consistent and standardized system of measurement across different fields of science.
The kilogram (kg) was originally defined as the mass of 1 liter of water at its freezing point in 1795. However, in 1889, it was redefined as the mass of a specific platinum-iridium alloy cylinder known as the International Prototype Kilogram (IPK), which is still used as the standard today.
The use of the kilogram (kg) as the SI-unit for mass allows for a more universally understood and consistent system of measurement, as the pound and ounce are not commonly used in scientific contexts. Additionally, the kilogram is a more precise unit of measurement compared to the pound and ounce.
Yes, the choice of SI-unit for mass can greatly impact calculations and measurements in science. The kilogram (kg) is a base unit in the SI system and is used in many formulas and equations in fields such as physics and chemistry. Using a different unit could result in errors or inconsistencies in these calculations and measurements.
