🧪 稀释比例计算器(1:n 配比、C₁V₁ = C₂V₂)Dilution Ratio Calculator (1:n Mixing, C₁V₁ = C₂V₂)
三种算法:按 1:n 的稀释比和想要的总量算出原液和水各需多少(可选“1 份原液 + n 份水”或“原液占总量 1/n”两种说法);由已知原液和水的体积求比例与浓度;或用 C₁V₁ = C₂V₂ 求需要的原液体积。本地处理。Three ways: from a 1:n ratio and the total you want, get how much concentrate and water to use (as 1 part concentrate plus n parts water, or concentrate as 1/n of the total); from known volumes, get the ratio and strength; or use C₁V₁ = C₂V₂ to find the concentrate volume.

如何使用「稀释比例计算器(1:n 配比、C₁V₁ = C₂V₂)」?How do I use the Dilution Ratio Calculator (1:n Mixing, C₁V₁ = C₂V₂) tool?
在「稀释比例计算器(1:n 配比、C₁V₁ = C₂V₂)」中,填写「算法」、「比例 1 : n 中的 n」、「比例的含义」、「想要的总量」、「原液体积」等参数,结果会随输入实时计算并显示在下方。In the Dilution Ratio Calculator (1:n Mixing, C₁V₁ = C₂V₂): Fill in "Method", "n in 1 : n", "Ratio meaning", "Total wanted", "Concentrate volume"; results are recalculated instantly as you type.
1:4 是什么意思?What does 1:4 mean?
说法有两种:多数清洁剂、园艺用品指 1 份原液加 4 份水(共 5 份,原液占 1/5);实验室有时指原液占总量的 1/4。请看产品说明,并在“比例的含义”里选择。It is used two ways: most cleaning and garden products mean 1 part concentrate plus 4 parts water (5 parts, concentrate 1/5); labs sometimes mean the concentrate is 1/4 of the total. Check the label and pick the meaning.
C₁V₁ = C₂V₂ 怎么用?How do I use C₁V₁ = C₂V₂?
稀释前后溶质的量不变,所以 V₁ = C₂ × V₂ ÷ C₁。量出 V₁ 的原液,加水到总体积 V₂ 即可。C₁ 和 C₂ 的单位要一致。The amount of solute stays the same, so V₁ = C₂ × V₂ / C₁. Measure V₁ of stock and top up with water to V₂. C₁ and C₂ must use the same units.
体积单位用什么?Which volume unit should I use?
任意单位都可以(mL、L、oz 等),结果使用相同的单位。Any unit works (mL, L, oz and so on); the results use the same unit.
能举个计算实例吗?Can you show a worked example?
例如在「稀释比例计算器(1:n 配比、C₁V₁ = C₂V₂)」中填 算法 = 按比例配制,比例 1 : n 中的 n = 4,比例的含义 = 1 份原液 + n 份水,想要的总量 = 500,结果区显示:原液:100;水:400;最终浓度:20 %;ℹ 按“1 份原液 + 4 份水”,共 5 份。For example, entering Method = Mix to a ratio, n in 1 : n = 4, Ratio meaning = 1 part concentrate + n parts…, Total wanted = 500 in the Dilution Ratio Calculator (1:n Mixing, C₁V₁ = C₂V₂) gives: Concentrate: 100; Water: 400; Final strength: 20 %; ℹ As 1 part concentrate plus 4 parts water, 5 parts in all.
