NIST SP811 deprecates the use of prefixes greater than one with the liter (and
prefixes less than one with the metric ton. As SP811 closely parallels
ISO31-0, it may have similar text, but I don't have a copy to confirm this.
The FPLA and UPLR both require the cubic meter and disallow the kiloliter in
net contents labeling, where the units are prescriptive ("these, and no
others"). Also disallowed for net contents are cL, dL, daL, and hL.
I personally would find a figure in cubic meters easier to visualize (for large
amounts) than kiloliters, or any larger prefix.
SAE metric practice TSB003 recommends the cubic dekameter for large volumes,
such as irrigation water, where it is roughly the same magnitude as the
Customary unit acre*foot (1.23 dam³). I would not want to see the megaliter
(ML) used for that.
