It can't. Gross tonnage is a measure of volume, while displacement is a measure of weight. The light ship displacement is equal to the total displacement minus the deadweight.

The Tonnage Act of 1789 was an act that levyed a 50 cents per ton tax on foreign ships entering American ports, 30 cents per ton on American built but foreigned owned ships, and 6 cents per ton on American ships.
The Tonnage act of 1789 was a tax levied on ships that were coming into ports within the United States. The tax was based on the weight of the ship.

The annual cargo tonnage is cca. 56 000 000 tonnes.
Hull displacement & wind speed.
The gross tonnage calculation is defined in Regulation 3 of Annex 1 of The International Convention on Tonnage Measurement of Ships, 1969. It is based on two variables, and ultimately a one-to-one function of ship volume:V, the ship's total volume in cubic meters (m3), andK, a multiplier based on the ship volume.The value of the multiplier K varies in accordance with a ship's total volume (in cubic meters) and is applied as a kind of reduction factor in determining the gross tonnage value - which does not have a unit such as cubic meters or tons. For smaller ships, K is smaller, for larger ships, K is larger. K ranges from 0.22 to 0.32 and is calculated with a formula which uses the common or base-10 logarithm: K = 0.2 + 0.02 x log 10 (V)Once V and K are known, gross tonnage is calculated using the formula, whereby GT is a function of V:GT = K x VAs an example, we can calculate the gross tonnage of a ship with 10,000 m^3 total volume.K = 0.2 + 0.02 x log 10 (10,000) = 0.2 + 0.02 x 4 = 0.2 + 0.08 = 0.28 Then the gross tonnage is calculated:0.28 x 10,000 = 2800 GT
