[edit] Ash plume heights should be measured in units of feet
Ash plume heights should use units of feet because aircraft flight levels use units of feet. It will be easier to compare ash plume heights with aviation flight levels if they use the same units. Since the metric terms are probably of use to geologists, they should be left in as conversions, following the British units, according to the second rule in Wikipedia:Manual of Style (dates and numbers) that says use the source units first and the converted values second.
