🪨 石料计算器（面积 × 厚度、体积、重量、袋数、费用）Stone Calculator (Area × Depth, Volume, Weight, Bags, Cost)

使用说明与常见问题How-to & FAQ

「石料计算器（面积 × 厚度、体积、重量、袋数、费用）」是什么？What is the Stone Calculator (Area × Depth, Volume, Weight, Bags, Cost) tool?

估算碎石、砾石、卵石、河石等石料用量：直接输入体积，或输入铺设面积和厚度（米/厘米或英尺/英寸）。按所选石料的堆积密度求重量（kg、吨、短吨），并给出立方码、袋数和费用估算。本地处理。Estimates crushed stone, gravel, pea gravel or river rock: enter a volume directly, or an area and depth in metres and centimetres or feet and inches. The bulk density of the chosen stone gives the weight in kg, tonnes and US tons, plus cubic yards, bag count and a cost estimate. Processed locally.

如何使用「石料计算器（面积 × 厚度、体积、重量、袋数、费用）」？How do I use the Stone Calculator (Area × Depth, Volume, Weight, Bags, Cost) tool?

在「石料计算器（面积 × 厚度、体积、重量、袋数、费用）」中，填写「输入」、「体积 m³」、「密度 kg/m³」、「石料类型（填入密度）」、「面积 m²」等参数，结果会随输入实时计算并显示在下方。In the Stone Calculator (Area × Depth, Volume, Weight, Bags, Cost): Fill in "Input", "Volume m³", "Density kg/m³", "Stone type (sets density)", "Area m²"; results are recalculated instantly as you type.

需要多少石料？How much stone do I need?

体积 = 面积 × 厚度。例如 10 m² 铺 5 cm 厚需要 0.5 m³；再乘以堆积密度（砾石约 1680 kg/m³）得到约 840 kg。Volume = area × depth: 10 m² at 5 cm deep is 0.5 m³. Multiply by bulk density (gravel about 1680 kg/m³) for about 840 kg.

一立方码石头多重？How much does a cubic yard of stone weigh?

大约 1.2–1.4 吨（2,400–2,900 lb），取决于石料种类和粒径。About 1.2–1.4 tonnes (2,400–2,900 lb), depending on the stone and its size.

铺多厚合适？How deep should I lay it?

装饰面层一般 5–8 cm（2–3 英寸）；车道基层约 10–15 cm；排水沟渠按设计。Decorative top layers are usually 5–8 cm (2–3 in), driveway base layers about 10–15 cm, and drainage trenches per the design.

能举个计算实例吗？Can you show a worked example?

例如在「石料计算器（面积 × 厚度、体积、重量、袋数、费用）」中填 体积 m³ = 2，密度 kg/m³ = 1600，结果区显示：质量 kg：3,200；吨：3.2For example, entering Volume m³ = 2, Density kg/m³ = 1600 in the Stone Calculator (Area × Depth, Volume, Weight, Bags, Cost) gives: Mass kg: 3,200; Tonnes: 3.2

哪些输入会被检查？Which inputs are validated?

「石料计算器（面积 × 厚度、体积、重量、袋数、费用）」会检查这些输入——「体积 m³」、「面积 m²」、「厚度 cm」、「长 ft」、「宽 ft」、「厚度 in」：所选方式用到时必须填写，须大于 0；「密度 kg/m³」：须大于 0；「每袋 kg（可选）」、「每吨单价（可选）」：不能为负数；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Stone Calculator (Area × Depth, Volume, Weight, Bags, Cost) checks its inputs — "Volume m³", "Area m²", "Depth cm", "Length ft", "Width ft", "Depth in": required when the chosen option uses it, must be greater than 0; "Density kg/m³": must be greater than 0; "Bag size kg (optional)", "Price per tonne (optional)": cannot be negative; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.

有哪些选项可以调整？What options can I adjust?

「石料计算器（面积 × 厚度、体积、重量、袋数、费用）」的设置：「输入」可选 体积、面积与厚度（米、厘米）、长宽（英尺）与厚度（英寸）（默认 体积）；「体积 m³」默认 2；「密度 kg/m³」默认 1600；「石料类型（填入密度）」可选 自定义、碎石 1600、砾石 1680、豆石 1520、河石 / 卵石 1450、石屑 / 道砟 2400 (压实)（默认 自定义）；「面积 m²」默认 10；「厚度 cm」默认 5；「长 ft」默认 10；「宽 ft」默认 10；「厚度 in」默认 3；「每袋 kg（可选）」默认 25；「每吨单价（可选）」可留空。每次生成结果都按当前设置处理。Settings in the Stone Calculator (Area × Depth, Volume, Weight, Bags, Cost) — "Input": Volume, Area and depth (m, cm), Length and width (ft), depth (in) (default Volume); "Volume m³" default 2; "Density kg/m³" default 1600; "Stone type (sets density)": Custom, Crushed stone 1600, Gravel 1680, Pea gravel 1520, River rock 1450, Compacted stone dust 2400 (default Custom); "Area m²" default 10; "Depth cm" default 5; "Length ft" default 10; "Width ft" default 10; "Depth in" default 3; "Bag size kg (optional)" default…
