Volumetric Weight:
1. Wherever the postage, tariff or charges are fixed for a postal
article based on weight , the weight shall mean the gross weight or the
volumetric weight whichever is more.
2. Gross Weight: Gross weight is the weight shown by a standard weighing
scale. When the Article is appropriately placed on to or suspended from
the said scale.
3. Volumetric Weight: volumetric weight of the article shall be arrived
at from the volume of that article using the appropriate formulae.
4. Exception: Volumetric weight need not be determined in following cases.
(a) If the sum of the length, breadth and height is not more than 90
centimeters, and any of the dimensions is not more than 60 centimeters.
(b) In case of an article is in roll form (Cylindrical) if the length and diameter each are less than 90 centimeters.
These exceptions will also applicable to Speed Post article.
5. Procedure for calculation of volume: Measure each dimension in centimeters rounded off to next higher centimeter.
(a) (i) Cuboids (e.g. square or Rectangular): Its Dimensions means length, Breadth and height.
(ii) Cylindrical rolls: Dimensions means diameter of its circular base and length.
(b) Articles other than above shapes should not be accepted.
(c) Formula for calculation of volumetric weight.
(i) Cuboids (e.g. Square, Rectangular)
Volume = Length X Breadth X Height
(ii) Cylindrical Roll.
Volume = 0.785 X (Diameter of Circular base)2 X Length
The Volume so arrived at in cubic centimeters should be rounded off to the next higher whole number.
6. Formula to calculate volumetric weight: When the volume is calculated
in cubic centimeters, the formula to determine the volumetric weight in
kilograms shall be :
Volumetric Weight in Kilo Gram = (Volume in Centimeters)3 ÷ 6000
Volumetric weight so arrived at shall be rounded off to the next higher kilogram.
7. Postage or tariff or charges for the Postal articles shall be
determined with reference to weight i.e. gross weight or volumetric
weight, whichever is more.
8. Postage/Tariff charts for all kinds of postal articles may be worked
out beyond the corresponding weight (as in gross weight) limits for
calculation of due postage/Tariff.
9. The maximum weight and size limits for different kinds of postal
articles are prescribed in Clause 100, 124, 125, 128(2), 129(2), 132,
137(d) and (e), 146(1) and (2) of Post Office Guide Part-I.

Examples:
Book packet in cuboids shape weighing 5 Kg (gross Weight) and with 60 Cms. Length, 30 Cms. Breadth and 30 Cms. Height.
Gross Weight: 5 Kg.
Volumetric Weight =
Length X Breadth X Height
6000
=
60 X 30 X 30
6000
=
54000 = 9 Kg.
6000
Additional postage beyond 5 Kg. and upto 9 Kg.
First 50 Gms. = Rs. 4/-
Remaining 8950 Gms. = Rs. 537/-
(@ Rs. 3.00 for 50 Gms.
Or part thereof) Total = Rs. 541/-
