❄️ BTU/h ↔ 冷吨BTU to Ton (Refrigeration)
英热单位每小时（BTU/h）与冷吨（制冷吨 RT）互算：1 RT = 12,000 BTU/h ≈ 3.51685 kW。本页是功率/制冷量，不是质量吨，也不是单一 BTU 能量。Convert BTU per hour ↔ refrigeration tons (RT): 1 RT = 12,000 BTU/h ≈ 3.51685 kW. This page is cooling power, not a mass ton and not single-BTU energy.

「BTU/h ↔ 冷吨」是什么？What is the BTU to Ton (Refrigeration) tool?
英热单位每小时（BTU/h）与冷吨（制冷吨 RT）互算：1 RT = 12,000 BTU/h ≈ 3.51685 kW。本页是功率/制冷量，不是质量吨，也不是单一 BTU 能量。Convert BTU per hour ↔ refrigeration tons (RT): 1 RT = 12,000 BTU/h ≈ 3.51685 kW. This page is cooling power, not a mass ton and not single-BTU energy.
如何使用「BTU/h ↔ 冷吨」？How do I use the BTU to Ton (Refrigeration) tool?
在「BTU/h ↔ 冷吨」中输入数值并选择原单位，表格会同时列出换算到所有其他单位的结果，可一键复制。Enter a value in the BTU to Ton (Refrigeration) and choose the source unit; the table shows the value in every other unit at once, ready to copy.
冷吨不是质量吨Not a mass ton
冷吨（ton of refrigeration）是空调/制冷里的功率单位：把 1 短吨 0°C 冰在 24 小时内融化所需的平均热流，定义为 12,000 BTU/h。本页没有「吨」作为 1000 kg 的质量换算。A refrigeration ton is a cooling-power unit used in HVAC: the average heat flow to melt 1 short ton of ice at 0°C in 24 hours, defined as 12,000 BTU/h. This page does not convert mass tonnes.
BTU/h 还是 BTU？BTU/h vs BTU
这里用的是功率（BTU 每小时）。若要把能量 BTU 换成 kWh，请用站点里的 BTU↔kWh 工具；二者差一个「每小时」。Here the unit is power (BTU per hour). To convert energy in BTU to kWh, use the site's BTU↔kWh tool - that is energy, not rate.
负值与零Zero and negatives
输入 0 会得到全 0；负值按同一系数换算（表示反向热流的符号约定由你自行解释）。系数采用 1 RT = 12,000 BTU/h、1 kW ≈ 3412.14 BTU/h。0 maps to all zeros; negatives scale with the same factors (sign of heat flow is up to you). Factors: 1 RT = 12,000 BTU/h, 1 kW ≈ 3412.14 BTU/h.
换算系数准确吗？Are the conversion factors exact?
「BTU/h ↔ 冷吨」采用国际单位制（SI）或公认标准中的定义值作为换算系数，结果保留约 10 位有效数字。The BTU to Ton (Refrigeration) uses factors defined by the SI or other recognised standards and shows about 10 significant digits.
