🏁 四分之一英里（直线加速）成绩估算器Quarter Mile Calculator
按常被引用的 Huntington 经验公式，由车重和马力估算 1/4 英里直线加速时间（ET）和终点速度：ET = 5.825 × (重量 ÷ 马力)^(1/3)，终速 = 234 × (马力 ÷ 重量)^(1/3)；也可由 ET 或终速反推马力。Estimate quarter-mile elapsed time and trap speed from weight and horsepower with the often-quoted Huntington rules of thumb, ET = 5.825 × (weight ÷ hp)^(1/3) and trap mph = 234 × (hp ÷ weight)^(1/3) — or back out horsepower from an ET or trap speed.

如何使用「四分之一英里（直线加速）成绩估算器」？How do I use the Quarter Mile Calculator tool?
在「四分之一英里（直线加速）成绩估算器」中，填写「求」、「车重（含车手，磅）」、「马力（hp，车轮或飞轮）」、「1/4 英里时间（秒）」、「终点速度（mph）」等参数，结果会随输入实时计算并显示在下方。In the Quarter Mile Calculator: Fill in "Find", "Weight with driver (lb)", "Horsepower (hp)", "Quarter-mile time (s)", "Trap speed (mph)"; results are recalculated instantly as you type.
公式从哪里来？Where do the formulas come from?
这是长期在直线加速圈流传的 Roger Huntington 经验公式：ET = 5.825 × (重量 ÷ 马力)^(1/3)，终速 = 234 × (马力 ÷ 重量)^(1/3)，重量按磅、含车手。它们是粗略估算，不是物理精确模型。They are Roger Huntington's long-circulated drag-racing rules of thumb: ET = 5.825 × (weight ÷ hp)^(1/3) and trap mph = 234 × (hp ÷ weight)^(1/3), with weight in pounds including the driver. They are rough estimates, not an exact physical model.
填飞轮马力还是车轮马力？Flywheel or wheel horsepower?
公式最初按飞轮（发动机）马力使用。如果填测功机测得的车轮马力，估算的 ET 会偏慢一些。The formulas were originally used with flywheel (engine) horsepower; entering dyno wheel horsepower will make the estimated ET somewhat slower.
结果可以代替医生的建议吗？Can this replace medical advice?
不能。「四分之一英里（直线加速）成绩估算器」基于常用公式给出估算，个体差异较大，如有健康问题请咨询医生或专业人士。No. The Quarter Mile Calculator gives estimates from common formulas; individuals differ, so consult a doctor or professional for health decisions.
