Feb 29. By now seemingly everybody has heard about John Oliver ripping Donald Trump a new, proverbial... Erm, well, anyway, Oliver had a lot to say on Last Week Tonight about The Donald, but one major portion of the segment covered Trump's familial name and how it changed upon entering the U.S. from Drumpf to Trump.
The kilogram or kilogramme (SI unit symbol: kg) is the base unit of mass in the International System of Units (SI) (the Metric system) and is defined as being equal to the mass of the International Prototype of the Kilogram (IPK, also known as Le Grand K or Big K).
When an object's weight (its gravitational force) is expressed in kilograms, this actually refers to the kilogram-force (kgf or kg-f), also known as the kilopond (kp), which is a non-SI unit of force. All objects on the Earth's surface are subject to a gravitational acceleration of approximately 9.8 m/s2.
