CREATE TABLE table_204_229 (id NUMBER, "property" CLOB, "test method" CLOB, "units" CLOB, "4275" CLOB, "4301" CLOB, "4435" CLOB, "4630" CLOB, "4645" CLOB)

how many times does mpa -lrb- kpsi -rrb- appear under the units column ?
SELECT COUNT(*) FROM table_204_229 WHERE "units" = 'mpa (kpsi)'
SELECT COUNT(*) FROM "table_204_229" WHERE "units" = 'mpa (kpsi)'
