The BTU input and output ratings are on the same tag as the model #.
90,000 BTUs - the 090 is what tells you the BTUs of the unit.
80000
Most likely 42,000 BTUs, 3-1/2 tons
The Trane model YCC036A1LOAA is a packaged rooftop unit that typically has a heating capacity of approximately 36,000 BTUs.

One liter of furnace oil contains approximately 36,000 BTUs (British Thermal Units). This measurement is a standard conversion for the energy content of furnace oil, which is commonly used for heating purposes. The BTU value may vary slightly depending on the specific composition and quality of the oil.

4800 BTUs will 150 square feet.
1 gal of #2 fuel oil (or diesel for that matter) has an equivalent of 115,000 BTUS. I say equivalent because it has a little more than that raw (like 136k or so) but the furnace that burns it is only around 85% efficient, therefore you only get 115K BTUS.
A small room is about 5,000 BTUs. Most people don't have a room that would require more than 10,000 BTUs.
