流量单位换算器
关于流量单位换算器的参考数据和工程信息，用于基础应用。
概述
本页面提供了液压、暖通空调等中使用的常见流体流量单位的换算系数 and process engineering. Conversion is always a simple multiplication — locate the source unit in the left column and multiply by the factor in the target unit's column. Common abbreviations include gpm (gallons per minute), gpd (gallons per day), cfm (cubic feet per minute), and l/s (litres per second).
关键公式
所有流量单位换算遵循相同的基本关系：

Common Engineering Conversions
| Conversion | Formula |
|---|---|
| m³/h → US gpm | Q_{\text{US gpm}} = Q_{\text{m^{3}/h}} \times 4.403 |
| m³/h → Imp gpm | Q_{\text{Imp gpm}} = Q_{\text{m^{3}/h}} \times 3.67 |
| CFM → m³/h | Q_{\text{m^{3}/h}} = Q_{\text{cfm}} \times 1.699 |
| US gpm → l/s | |
| l/s → m³/h | Q_{\text{m^{3}/h}} = Q_{\text{l/s}} \times 3.6 |

Alternative Flow Units
The source also lists alternative flow units used outside the main SI and Imperial conversion tables. The table below preserves those alternatives as equivalents of 1 m³/s so they can be compared directly with the primary units.

Complete Flow Conversion Matrix
The following matrix consolidates the source flow-unit converter tables so each row can be checked directly. Multiply a source-unit value by the target-column factor.
Source table coverage: the Imperial/US table, the Metric/SI table, and the alternative-units table are preserved above and consolidated below. Source row labels that are aliases, such as CFM and ft3/min, are represented explicitly as conversion rows or chart labels; the restored alternative table keeps the remaining non-primary units.

工程要点
- US vs Imperial gallons: A US gallon equals 3.785 litres, while an Imperial (UK) gallon equals 4.546 litres. Always verify which gallon is intended — confusing the two introduces a ~20% error.
- Volumetric vs mass flow: These tables cover volumetric flow only. Mass flow conversions require fluid density, which varies with temperature and pressure.
- Temperature dependence: Volumetric flow rates for gases are strongly temperature- and pressure-dependent. The conversion factors here are exact ratios between unit definitions and apply regardless of conditions, but the measured flow itself may need correction to standard conditions (e.g. SCFM at 15.6 °C and 1 atm).
- Precision: Conversion factors are given to the precision typically needed in engineering practice. For metrology or calibration work, use the exact definitions (1 ft = 0.3048 m, 1 US gal = 231 in³).
- Common pipeline convention: In oil and gas, barrels per day (bbl/d) is standard: 1 m³/h ≈ 151 bbl/d.
