What is a Kilogram?
A kilogram (kg) is the standard unit of mass in the International System of Units (SI). Initially defined by the International Prototype Kilogram, this unit has been redefined over the years to be more precise. As of May 20, 2019, the kilogram is now defined in terms of fundamental physical constants, making it a more universally consistent measurement.
Interesting Fact:
- Did you know? A kilogram is now defined by the Planck constant (h), which relates the energy of a photon to its frequency, rather than being based on a physical object.
What is a Pound?
The pound (lb or lbs) is a unit of mass used in the imperial and US customary systems. It's derived from the Latin word 'libra', which is why the abbreviation 'lb' is used. One pound is equal to 16 ounces or 7,000 grains.
Practical Example:
