The CONVERT_ADD function returns 2ml (milli liter) for 1 tspm (modern teaspoon) instead of the correct 5ml.
Created attachment 68229 [details] proposed patch On pc Debian x86-64 with 3.6 branch updated today, I reproduced the pb. I propose this patch. The only problem is other measures seem wrong, for example "tsp". So even I missed something, even the conversion values must be (all?) checked.

Created attachment 68234 [details] Conversion table OASIS-LO see comment Attached a CALC sheet containing a fusion of OASIS Convert Table and LO implementation (Sheet2). Sheet1 is LO table as used in CALC-Help corrected with missing stuff. You can use it to insert in help-files if you want. "tsp" looks ok to me 1/6 oz as defined.
Sorry, you were right Horst (see http://en.wikipedia.org/wiki/Cooking_weights_and_measures)
