万标立方米是气体密度测量单位，是指10000标立方米。

标立方米的意思是：

The most common units of industrial gas measurement are; SCFH and Nm3/hr. Note, that there is a difference between Normal cubic meters and Standard cubic meters. The difference lies in the reference temperature that each specific unit is measured with respect to. Normal meters are measured with respect to the Metric system (00C, 1 atm), and standard meters are measured with respect to the imperial system of standard conditions (700F, 1atm).

1 Normal Cubic Meter equals 38.042 SCF：1立方米等于38.042立方英尺。

（不太懂）

标立方米是气体密度测量单位

SCFH ：风量单位:立方英尺/小时

Nm3/hr：立方米每小时，体积流量单位。

1M3/H=0.5886CFM(立方英尺每小时)

1M3/H=0.2778LPS(升每秒)

立方米和标立方米有差异：

差异在于每一个具体单位关于被测量的温度。

（Normal meters are measured with respect to the Metric system and standard meters are measured with respect to the imperial system of standard conditions (700F, 1atm).）

正常的立方米是公制标准测量(00C, 1 atm), 标准的米是英国皇家标准测量。
