Uma for\u00e7a resultante pode alterar o movimento de um objeto; na mec\u00e2nica cl\u00e1ssica, \\(F=ma\\) relaciona a for\u00e7a resultante, a massa e a acelera\u00e7\u00e3o. Uma convers\u00e3o de for\u00e7a n\u00e3o altera a for\u00e7a f\u00edsica \u2014 apenas o n\u00famero e a unidade usados para a exprimir.<\/p>\n<p>O newton (N) \u00e9 a unidade <em>derivada<\/em> de for\u00e7a do SI: \\(1\\ \\mathrm{N}=1\\ \\mathrm{kg\\,m\/s^2}\\). Os kilonewtons (kN) s\u00e3o pr\u00e1ticos para cargas maiores, enquanto as dinas (dyn) pertencem ao sistema cent\u00edmetro-grama-segundo (CGS). A libra-for\u00e7a (lbf), a on\u00e7a-for\u00e7a (ozf) e os kips s\u00e3o usados em algumas especifica\u00e7\u00f5es que empregam unidades consuetudin\u00e1rias. Um kip significa mil libras-for\u00e7a.<\/p>\n<p>O quilograma-for\u00e7a (kgf) e o grama-for\u00e7a (gf) designam for\u00e7as, n\u00e3o massas. Por exemplo, 1 kgf \u00e9 a for\u00e7a correspondente a uma massa de 1 kg sob a gravidade padr\u00e3o, definida aqui como \\(9.80665\\ \\mathrm{m\/s^2}\\). Um quilograma (kg), por si s\u00f3, \u00e9 uma unidade de massa, portanto, n\u00e3o substitua um valor de massa por um valor de for\u00e7a sem considerar a acelera\u00e7\u00e3o.<\/p>\n<p>A consist\u00eancia das unidades \u00e9 importante ao comparar uma carga medida com uma capacidade nominal ou ao usar uma for\u00e7a em outro c\u00e1lculo. Para uma for\u00e7a aplicada a uma certa dist\u00e2ncia de um ponto de apoio, consulte o <a href=\"https:\/\/wpcalc.com\/pt\/conversores\/conversor-de-torque\/\">conversor de torque<\/a>.
