千克力(kilogram-force)就是公斤力,是力的一种常用单位,力的国际单位是牛顿。1千克力指的是1千克的物体所受的重力。所以1千克力≈9.8牛顿。千克力的符号为:kgf、kg、kp。 千克力和千克不是一个概念,千克力是力的单位,千克是质量的单位。
虽然只有不到800袋咖啡豆(每袋60千克,或132磅)在巴西进行拍卖,对于世界年产量1亿袋来说根本微不足道,但杯测比赛还是产生了不小的影响力。
With just under 800 bags of coffee (of 60kg, or 132lb, each) in its Brazil auction, Cup of Excellence is insignificant alongside worldwide production of around 100m bags a year. Yet it is influential.
比如,质量单位千克,热力学温度开尔文,能量单位焦耳,电流强度单位安培,力单位牛顿等。
Such as kilogram of mass unit , Kelvin of thermodynamic temperature , Joule of energy unit , Ampere of electric current intensity and Newton of force unit and so on?
当黑洞内部的物质的密度到达巨大的程度(超过1050千克每立方米)时,扭曲显现出一种反引力的力。
When the density of matter reaches gargantuan proportions (more than about 1050 kilograms per cubic metre) inside a black hole, torsion manifests itself as a force that counters gravity.
So, the way to measure force is in kilogram meters per second squared.
所以,力的单位是千克米每秒平方
Here is some object, it's 5 kilograms and I apply 10 Newtons.
这有一个物体,5 千克,我对它施加 10 牛的力
I got 2 kg and I pull this guy with 10 Newtons.
还有一个 2 千克的物体,我用 10 牛的力来拉它
