In, invalid range option "disp=nocomma" – use range-words "tonocomma" or "xxnocomma" (etc.) to suppress commas. See:. The option "disp=nocomma" does not work in ranges because commas are forced into the results depending on the range-word (to, or, and, xx, by, etc.). Instead, use the range-words with suffix "nocomma" as follows:
 * {&#123;convert|2000|tonocomma|5000|ft|m}} &rarr; 2000 tonocomma
 * {&#123;convert|2000|to|5000|ft|m}}&rarr; 2000 to 5000 ft
 * {&#123;convert|9800|xxnocomma|11700|ft|m}} &rarr; 9800 xxnocomma
 * {&#123;convert|3300|andnocomma|7600|ft|m}} &rarr; 3300 andnocomma
 * {&#123;convert|1250|bynocomma|2450|ft|m}}  &rarr; 1250 bynocomma

The option "disp=nocomma" only works for 1-unit conversions, not for 2-unit ranges of units.
