Derived at origin station in Dhaka. Source information given to 3 decimal places but rounded by OGP to be commensurate with stated accuracy. For consistency with Survey of Bangladesh, Gulshan 303 to WGS 84 (2) [code 9679] should be preferred.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4682", "EPSG:4326", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
