It is a measurement of the relative
bulk of paper for a given grammage. The higher the volume
number the bulkier the stock. The basis is that 10 leaves
of 100gsm Volume 10 = 1mm.
How do I calculate the thickness of a title?
No. of pp x volume no. x grammage
20,000
= Bulk in mm
How does caliper relate to volume?
Caliper in microns =
volume no. x grammage 10

calculations
To calculate the cost in £ per 1000 sheets if given
the price per tonne (1000kg) and weight per 1000 sheets
:
Price in £ per tonne x kg per 1000
sheets 1000
To calculate the number of tonnes from a number
of sheets :
Area x grammage x number of sheets
in 1,000s 1000
To calculate the cost per 1000 sheets if given
the price in pence per kg and weight in kg per 1000
sheets :
Price in pence per kg x kg per 1000
sheets 1000
To calculate the cost per 1000 sheets of a size
in mm given the price in
£ per square metre :
Price x sheet dimensions 1000
To calculate volume where caliper and substance
are known :
Caliper (micrometers) x 10
g/m2
= Volume
To calculate the price per 1000 sheets for a certain
tonnage :
1st dimension (mm) x 2nd dimension
(mm) x g/m2 1,000 000
= kg per 1000 sheets
Followed by :
Price per tonne x kg per 1000 sheets 1000
= Price per 1000 sheets
To calculate the grammage, given sheet size in
mm and weight in kg per 1000 sheets :
kg per 1000 sheets x 1,000,000 length in mm x width in mm
To obtain weight in kg per 1000 sheets, given the
sheet size in mm and grammage:
Length in mm x width in mm x g/m2 1,000,000
To calculate the number of sheets per tonne (1000kg)
given kg per 1000 sheets of the paper :
1,000,000 kg per 1000 sheets
To calculate weight in kg of quantity ordered in
sheets, given weight in kg per 1000 sheets :
kg per 1000 sheets x number of sheets 1000
To convert weight in per 1000 sheets in one size
to kg weight per 1000 sheets in another size :
given weight x dimensions of unknown
size dimensions of given size
