使用流程

Use this guide when a converted number affects pumps, irrigation, HVAC notes, tank filling, and process estimates. A reliable result keeps the original value, source unit, target unit, conversion factor, and rounding choice visible.

The goal is not to memorize every factor. The goal is to make the calculation traceable enough that someone else can review it later.

检查清单

Convert volume and time units separately when needed.
Use average flow only when variations do not matter.
Confirm whether the source uses US gallons or imperial gallons.

实用事实

Flow rate is a compound unit, so both the numerator and denominator can change.

实用示例

60 L/min equals 3.6 m3/h.

1 US gal/min is about 3.78541 L/min.

Flow rate x time gives total volume.

常见问题

What should I check first?

Confirm the source unit and target unit before changing the number.

When should I round?

Round at the end, after formulas and related conversions are complete.

重点

A useful conversion is traceable: it shows the original unit, the target unit, the factor used, and the rounding decision.
