# Brass ka Funda

Dear  Friends ,

Overview :
Although in a previous article , we have seen the use of the term brass in context of various measurements at site , let us understand the term in new background with fresh examples .

Questions :
1. What is the meaning of Brass ?
2. How do we measure the Brass ?
3.If the rates given are in Brass , how do we convert this into CuM and vice versa ?
4. Some tips for accurate measurements of the Brass at the site
Introduction :
The term Brass is numeric . Just like Dozen means 12 , the term Brass means 100 .
This term is used only when the measurements are in British units .
It is used both for area ( Sqft .) and Volume ( CFt ).
Example in Area ( British units ):
Suppose one slab measures 80′ long and is 40′ wide.
The area is 90′ X 40′  = 3200 Sqft.
So , we shall say that the slab area is 3200/100 = 32 Brass.

Example in Volume ( British units ):
Assume that there is a truck carrying sand .
The dimensions of the truck are :
15 ‘ long , 8′ wide and the depth of sand is 3’. ( measured by a rod )
The volume of the sand shall be 15 ‘ X 8’ x 3 ‘ = 360 CFt.
So , we shall say that the volume of sand in the truck is :
3600/100 = 36 Brass.

Remember that this term is not used with reference to Metric units .

Example in Area ( Metric units ):

Let us assume that there is a slab of length :8 M and width 4m.
The area of the slab is : 8M x 4 m = 32 SqM.
We can say that the slab area is 32 SqM and shall not say this in Brass.
But someone insists that this area ( 32 SqM ) be expressed in Brass , we proceed as follows :
Step 01 : Convert this area into sqft.
32 SqM x 10.76 Sqft. = 344.32 Sqft.
Step 02 : Divide this area by 100 to express it in Brass.
344.32/100 = 3.44 Brass.

Thus , we can say that a slab of  32 SqM.( 8M x 4 m  )is actually 3.44 brass.
Or , we can also say that 1 Brass ( = 32/3.44 ) = 9.302 SqM

Example in Volume ( Metric units ):

1.Suppose a supplier quotes the rate of sand as Rs.6000 per Brass.
This means 6000/100 = Rs.60 per Cft.
We know that 1CuM = 35.29 Cft.
Therefore , the rate  shall be  60 x 35.29 = Rs.2117.4 per CuM

2. Suppose we get a rate of aggregate as Rs, 1500 per CuM and this has to be expressed in Brass.
How do we proceed ?
Step 01 : Convert this into per Cft.
Rs.1500 per CuM means 1500 / 35.29 = 42.504 Rs./Cft.
Therefore , the rate per Brass shall be 42.504 X 100 = 4250.4 Rs./Brass .

Practice questions :
1. What is the area in Brass for a floor of size 140′ X 25′ ?
( Answer : 35 Brass )
2. What is the volume of a truck of dimensions : 18′ X 8′ x 5′ ?
( Answer : 72 Brass )
3. Express the rate Rs.4500 per Brass into per CuM ?
( Answer : 1588.05 per CuM )
4. Express the rate Rs.2500 per CuM into per Brass ?
( Answer : 7084.16  per Brass  )

Friends , hope you have now correctly understood the concept behind the Brass in a practical way.

The more often you use this , the better you shall understand this .

All the best !
