Selecionar a mesma unidade nos dois menus mant\u00e9m o valor num\u00e9rico inalterado.<\/p>\n<h2>O que significa torque<\/h2>\n<p>O torque descreve a tend\u00eancia de uma for\u00e7a para rodar um objeto em torno de um eixo. Aplicar uma for\u00e7a mais afastada do eixo geralmente cria mais torque: uma chave inglesa comprida facilita a rota\u00e7\u00e3o de um fixador em compara\u00e7\u00e3o com uma curta quando se aplica a mesma for\u00e7a perpendicular. O torque \u00e9 usado em especifica\u00e7\u00f5es de fixadores, motores, caixas de velocidades e equipamentos rotativos.<\/p>\n<p>Para uma for\u00e7a aplicada a uma certa dist\u00e2ncia do eixo de rota\u00e7\u00e3o, o m\u00f3dulo do torque \u00e9 \\(T=rF\\sin\\theta\\), onde \\(r\\) \u00e9 a dist\u00e2ncia at\u00e9 ao ponto de aplica\u00e7\u00e3o, \\(F\\) \u00e9 a for\u00e7a e \\(\\theta\\) \u00e9 o \u00e2ngulo entre as dire\u00e7\u00f5es da dist\u00e2ncia e da for\u00e7a. O conversor n\u00e3o calcula o torque a partir dessas medidas; converte um valor de torque j\u00e1 existente entre unidades. Se precisar primeiro de converter um valor de for\u00e7a, utilize o <a href=\"https:\/\/wpcalc.com\/pt\/conversores\/forca\/\">conversor de for\u00e7a<\/a>.<\/p>\n<p>O newton-metro (N\u00b7m) \u00e9 a unidade do SI usada para o torque. A libra-for\u00e7a p\u00e9 (lbf\u00b7ft) e a libra-for\u00e7a polegada (lbf\u00b7in) expressam o torque usando for\u00e7a em libras-for\u00e7a e dist\u00e2ncia em p\u00e9s ou polegadas. O quilograma-for\u00e7a metro (kgf\u00b7m) usa o quilograma-for\u00e7a, que n\u00e3o \u00e9 o mesmo que um quilograma de massa. Mantenha as partes de for\u00e7a e de dist\u00e2ncia de cada unidade juntas ao ler uma especifica\u00e7\u00e3o.<\/p>\n<h2>Fatores de convers\u00e3o e limites pr\u00e1ticos<\/h2>\n<p>Cada fator abaixo indica o valor de uma unidade em N\u00b7m. Para converter para N\u00b7m, multiplique pelo fator. Para converter a partir de N\u00b7m, divida pelo fator. A calculadora usa estes fatores para todos os pares de unidades.<\/p>\n<table>\n<thead>\n<tr>\n<th>Unidade<\/th>\n<th>1 unidade em N\u00b7m<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Newton-metro (N\u00b7m)<\/td>\n<td>1<\/td>\n<\/tr>\n<tr>\n<td>Quilonewton-metro (kN\u00b7m)<\/td>\n<td>1000<\/td>\n<\/tr>\n<tr>\n<td>Newton-cent\u00edmetro (N\u00b7cm)<\/td>\n<td>0,01<\/td>\n<\/tr>\n<tr>\n<td>Quilograma-for\u00e7a metro (kgf\u00b7m)<\/td>\n<td>9,80665<\/td>\n<\/tr>\n<tr>\n<td>Libra-for\u00e7a p\u00e9 (lbf\u00b7ft)<\/td>\n<td>1,3558179483<\/td>\n<\/tr>\n<tr>\n<td>Libra-for\u00e7a polegada (lbf\u00b7in)<\/td>\n<td>0,112984829<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Verifique a unidade com aten\u00e7\u00e3o antes de introduzir um n\u00famero.

Os menus n\u00e3o incluem a on\u00e7a-for\u00e7a polegada, pelo que um valor dado nessa unidade precisa de uma convers\u00e3o separada antes de poder ser introduzido aqui.<\/p>\n<p>O campo de entrada aceita valores iguais ou superiores a zero. O resultado apresentado \u00e9 arredondado a no m\u00e1ximo 10 casas decimais, pelo que resultados muito pequenos mas n\u00e3o nulos podem aparecer como zero. Para ajustes cr\u00edticos, siga a unidade, a toler\u00e2ncia e as instru\u00e7\u00f5es de arredondamento indicadas pelo fabricante do equipamento, em vez de acrescentar precis\u00e3o impl\u00edcita numa convers\u00e3o.<\/p>\n<p>O torque est\u00e1 relacionado com o movimento rotativo, mas converter as suas unidades n\u00e3o determina a rapidez com que um veio roda nem como acelera.
