CREATE TABLE table_203_356 (id DECIMAL, "type" TEXT, "diagonal  ( mm ) " TEXT, "width  ( mm ) " TEXT, "height  ( mm ) " TEXT, "area  ( mm2 ) " TEXT, "stops  ( area ) " DECIMAL, "crop factor" TEXT)

how long is the diagonal size of a 1/10 sensor ?
SELECT "diagonal (mm)" FROM table_203_356 WHERE "type" = '1/10"'
SELECT "diagonal (mm)" FROM "table_203_356" WHERE "type" = '1/10"'
