一立方码等于多少立方英尺？

27 立方英尺。立方码是边长 3 英尺的正方体，3 × 3 × 3 = 27。除数让人意外，是因为体积按边长的三次方变化。

如何把英寸深度换算成立方码？

先把英寸除以 12 换成英尺，再乘长宽并除以 27。在下方把单位选为英寸，计算器会自动完成。

一辆自卸车能装多少立方码？

双轴自卸车一般装 10–14 立方码，按 12 估算比较稳妥。材料潮湿或密实时，往往先到载重上限。

一立方码相当于多少袋混凝土？

约 45 袋 80 磅装，或 60 袋 60 磅装。超过半立方码后，预拌混凝土通常更便宜，也省力得多。

一立方码等于多少立方米？

一立方码等于 0.7646 立方米。计算器同时显示两者，这在技术资料为公制而供应商用英制时很关键。

yd³ = (长 ft × 宽 ft × 深 ft) ÷ 27   ·   深度英寸 ÷ 12 = 英尺

参考资料

Measure what the tool asks for
This calculator works from 长度 in ft, 宽度 in ft and 每立方码单价（选填） in $. Measure the finished area you are covering, not the material — an estimate is only as good as the dimensions you feed it.
What it does with those numbers
yd³ = (长 ft × 宽 ft × 深 ft) ÷ 27 · 深度英寸 ÷ 12 = 英尺 Every figure on the page comes out of that one expression, so you can check it by hand.
Why it adds 0% waste
这是纯粹的体积换算，请另行叠加所用材料要求的损耗系数。
Choosing a 深度单位
The 深度单位 changes the result, so pick the one that matches what you are actually buying rather than leaving the default.
Where the numbers come from
The constants are taken from NIST — Units of volume and capacity and NRMCA — Concrete in Practice: ordering concrete, linked in full below. If a figure here disagrees with your supplier's spec sheet, use the spec sheet — it describes the product you are buying.
What this will not tell you
This is a material takeoff, not a bid. It does not price labour, permits, delivery, equipment hire or site preparation, and it assumes a straightforward layout. Complex cuts, difficult access and awkward shapes all cost more than the geometry suggests.
