As Uwe notes, Raptor 2's thrust is higher than the figure you gave, about 2.3 MN.
Thrust and weight are both measured in force units -- Newtons in metric, pounds-force in US customary units. 2.3 MN of thrust can lift 2.3 MN of weight. The gravity you're trying to lift against is the conversion factor between mass in grams and force in Newtons. Dividing 2.3 MN by Earth's gravity, 9.81 m/s2, yields 235000 kg.
Thus, each Raptor can lift 235 metric tons from Earth's surface, and a 33-engine booster at full throttle can lift as much as 7,755 tons.
That thrust is more than 150% of the Earth-surface weight of the 5,000 ton Starship/Super-Heavy stack, so it will lift off easily.
The other way you could calculate this is by multiplying the TWR of the engine by the engine's mass: 140 x 1600kg = 224000 kg. Presumably the difference is due to rounding-off of the TWR and engine mass figures.
