Tudo come\u00e7ou quando James Watt \u2013 o homem que aprimorou a m\u00e1quina a vapor \u2013 definiu 1 Hp (Horse Power) : pot\u00eancia necess\u00e1ria para levantar a 1 metro de altura, por 1 segundo, uma massa de 75 kg.<\/span><\/p>\n

Cada pa\u00eds, a partir da\u00ed, imprimiu sua cara na medida. Unidades parecidas foram inventadas, mas estas podem ser confundidas facilmente.<\/span><\/p>\n

\"POTENCIA2\"<\/a><\/p>\n

HP:<\/strong> Valor medido no eixo motor com os acess\u00f3rios necess\u00e1rios para lig\u00e1-lo e funcionar de maneira aut\u00f4noma.<\/span><\/p>\n

BHP:<\/strong> Brake Horse Power: Normas americanas j\u00e1 obsoletas. Prefer\u00eancia das montadoras que vendiam pot\u00eancia. Foi abandonada em 1972.<\/span><\/p>\n

PS: <\/strong>abrevia\u00e7\u00e3o da palavra alem\u00e3 \u201cPferdest\u00e4rke\u201d, que significava cavalo-vapor. Diferia um pouco do hp por ser baseado no sistema m\u00e9trico ao inv\u00e9s do imperial.<\/span><\/p>\n

CV:<\/strong> Cheval Vapeur: Como a outra forma de se referir a pot\u00eancia (Pferdestarke) era dif\u00edcil de falar, os franceses inventaram o CV.<\/span><\/p>\n

W ou kW:<\/strong> \u00c9 a unidade padr\u00e3o do Sistema Operacional de Medidas (SI) definido pela Organiza\u00e7\u00e3o Interna para Normatiza\u00e7\u00e3o (ISO) segundo as normas ISO 31 e ISO 1000.<\/span><\/p>\n

O kW \u00e9 a medida utilizada pelas marcas alem\u00e3s. Os ingleses e americanos optam pelo HP. Os italianos e franceses, pelo CV, assim como os brasileiros.<\/span><\/p>\n

Equival\u00eancia das medidas:<\/span><\/p>\n

1 HP = 745,7 W ou 0,7457 kW<\/span><\/p>\n

1 CV (ou PS) = 0,7355 kW<\/span><\/p>\n

1 HP = 1,0138 CV (ou PS)<\/span><\/p>\n

Um erro comum que ocorre \u00e9 n\u00e3o converter os dados de CV para HP. Os dois n\u00e3o apresentam muita diferen\u00e7a se o valor for baixo. Por exemplo, 80 HP equivalem a 81,109 CV. Se o valor for mais alto, entretanto, a diferen\u00e7a come\u00e7a a ficar not\u00e1vel. 577 HP equivalem a 585 CV.<\/span><\/p>\n

Algumas montadores n\u00e3o distinguem os dois, por isso, prefira sempre se basear em kW. Ferramentas Online ajudam bastante. A WebCalc, por exemplo, \u00e9 dispon\u00edvel para smartphones e converte as medidas. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
