![]() Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. Weight and Gravitational Force When an object is dropped, it accelerates toward the center of Earth. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. Although almost the entire world uses the newton for the unit of force, in the United States, the most familiar unit of force is the pound (lb), where 1 N 0.225 lb. Conversion of units describes equivalent units of mass in other systems.Ĭonversion calculator for all types of measurement units. A gram is defined as one thousandth of a kilogram. The kilogram or kilogramme, (symbol: kg) is the SI base unit of mass. ![]() It was first used around 1904, but not until 1948 was it officially adopted by the General Conference on Weights and Measures (CGPM) as the name for the mks unit of force. Kilogram-force is unit of force in a gravitational metric system. In physics, the newton (symbol: N) is the SI unit of force, named after Sir Isaac Newton in recognition of his work on classical mechanics. one newton force is equal to 0.1019716213 kilogram-force. Kg to N, or enter any two units below: Enter two units to convert From: Besides, I'm not sure what leads anyone to think that g can be calculated to this many decimal places - moving around from continent to continent will result in different g values that differ by roughly 1%.You can do the reverse unit conversion from Most of the best measurements at the Earth's surface put the g number at about 9.81, but this may vary around a bit because the Earth isn't exactly a sphere, and so fourth.Īll of these web pages that seem to be giving you the same value of 9.80665002864 must be getting their information from the same source. The fact is that g has never had any defined value to speak of (unlike the speed of light, but that's another story). Now, on to the part you asked about the number of decimal places, accuracy, and g being "defined" as 9.80665. Now, if we limit our question to "how many Newtons would a 1kg object weigh at the Earth's surface", then yes I suppose there is a conversion between the two, and yes that conversion is about 9.81 m/s^2. Reduced to base units in the International System of Units ( SI ), a kilogram-meter per second is the equivalent of a newton-second (N s), which is the SI. These two may seem like they are exactly the same thing, but they are just different enough to be completely different things. Kilograms is a unit of mass (how much matter is in an object) while Newtons is a measure of the force that the Earth's gravity exerts on the object. We concluded from our explanation of the relationship between Kg and Newton that they are directly proportional. What gives?įirst off, the others posting answers to this question are ultimately correct - there really is no direct conversion between kilograms and Newtons. Thus, a kilogram of force equals 9.81 Newtons. Most all of them seem to give 9.80665002864 meters/sec^2. However, I found numerous sources on the web that seem to give the exact same answer for g, the acceleration due to gravity. I thought that it was 9.80665 by definition. How many Newtons are in a kilogram, exactly. If you don't mind, I need to tidy up your question just a bit: There are a couple of misunderstandings in your questions, but I think I can see what is ultimately being asked. Kilogram is the base unit of mass in the metric system. To simply convert from any unit into newtons, for example, from 20 kilogram-force, just multiply by the conversion value in the right column in the table.
