What is the unit for the oil quantity display in the Airbus A320 ECAM?

Is this image showing 18.5 liters or quart of engine oil?

• Welcome to Aviation.SE. Could you edit your question and add the type of aircraft you are asking for? – Noah Krasser Sep 26 '18 at 7:39
• Thanks. I edit it to A320. Eng Cfm 56-5B – Hồng Văn Nguyễn Sep 26 '18 at 7:56
• It's right there on the screen. It says OIL and right below it it says QT. Probably more obvious to an American who is used to this archaic unit of measure, but the F. USED label is also identified in KG right above it... – FreeMan Sep 26 '18 at 19:09
