"Ea măsoară un cuptor."
Translation:She measures an oven.
Measuring its dimensions. I know it sounds weird because you don't do that every day, but she's probably furnishing her kitchen and looking for a new oven at the store, with her trusty measuring tape ready for action. Yup, typical Romanian scenario. :-)
PS: "She measures the oven temperature." = "Ea măsoară temperatura cuptorului."
