Nautical Almanac 1992 (Selected Tables)
This old edition is being used by Indian students for examination purposes only. Questions are prepared on basis of this Nautical Almanac
This publication is a type of navigation aid, which describes the position of celestial bodies to assist navigators at sea to determine their ship's position using celestial navigation

The nautical almanac contains astronomical data for the entire year which assists the navigator in making astronomical calculations on ship. Reading the bullet points will be easier if one has the almanac open in front for easy reference.

A nautical almanac uses the time position as per the GMT (Greenwich Meridian Time) along with the position of the earth to calculate and predict the sea-routes. The position of the sun, the moon, the other planets and 57 main stars are also used along with the GMT and the earth’s position to calculate the potential navigational routes.

ASTM Tables - Selected pages
In 1980, the American Society for Testing and Materials (ASTM) together with the London Institute of Petroleum (IP) and the American Petroleum Institute (API), introduced the new API/ASTM-IP Petroleum Measurement Tables (further ASTM tables).
These tables are used for calculating volumes and weights of petroleum oil to a specific standard temperature.
These methods are mostly used for calculation of chemical cargoes. But for petroleum products and crude oils, ASTM tables are used for calculating cargo weights. ASTM tables give the Volume correction factors (VCF) to find the volumes at temperature for which the density is provided.
