One of the most common questions I get asked often is “how to calculate CBM and freight ton”, specially by those clients who get charged per Freight Ton or Revenue Ton..

Firstly CBM stands for **C**u**B**ic **M**eter.. This is the most common unit used for the measurement of volumetric cargo.. Metric Tons as you know refers to the weight of cargo (1 Metric Ton = 1000 Kilograms)..

Freight Ton or Revenue Ton is derived by calculating the weight or volume of the cargo and the freight is charged based on whichever is higher..

When you have the dimensions of the package, first of all convert the measurement into meters..

Normally dimensions are in Length x Width x Height..

If for example the dimensions of a cargo crate is

3.2 x 1.2 x 2.2 meters then the CBM is simply 3.2 x 1.2 x 2.2 = 8.448 CBM..

As mentioned above, if the rate is quoted as for example USD.12/per freight ton and the weight of the package is 1200 kgs = 1.2 tons, then the freight rate for this will be

8.448 cbm x USD.12 = USD.101.376 or

1.2 tons x USD.12 = USD.14.4

Since the CBM rate is higher, the freight rate of USD.101.376 will apply..

How to get the chargeable weight from CBM to AIR FREIGHT

Dear All,

thanks all for sharing good info. here raised a question in my mind that why we divide 61024 to dimension when dimension is in inch. or why why we divide by 1000000 when dimension is in c,m. where as in meter there is no need of any division. actually what is 61024 and 10000. please let me know?

Dear Hariesh Manaadiar,

Hera i m going to answer your question.. what does 61024 stands for?

Actually 61024 is used to to calculate CBM while dimesions are in inches. first we need top convert inches into meter. in one meter there are 39.3701 inches. so when we calculate cbm while dimensions are in inch that time we mutiply

39.3701 X 39.3701 X 39.3701 = 61024.

eg

L = 23” W = 12” H = 8”

L X W X H / 61024

23/39.3701 X 12/39.3701 X 8/39.3701

0.036 CBM

THIS IS CBM FOR 1 CARTON.

I think it ll be hlpfl for u

I have the simple formula to calculate the CBM-

Dimension in Inches – Length x Width x Height x No. of Carton / 61024

Its really helpful

Hi Darpan, what does the 61024 represent..??

We calculate LCL shipments by taking the item or items that you would like to purchase and calculate their given volumes. To do this we first take the length, width, and depth of each piece and add from 1-4 inches to each dimension. We add the 1-4 inches to the size of the pieces to allow for packing and framing. Once we get the total volume of the piece or pieces you are ordering we divide the total volume by 61,024

We get the 61,024 figure from length 39.37 inches multiplied by width 39.37 inches multiplied by Depth 39.37.

thnks so much abt all inf.above

Could you pls let me know who can issue SEAWAY bill.

I used to receive SWB from carrier but never get it from freight forwarder. if so just Carrier can issue SWB? and FWD just issue surrender bill? hope to get your feedback. thnks in advance.

Hi Hariesh!,

I would like to know why the shipping lines are charging different rates on demurrage on different occasions, for the same amount of time and same size of container?. Will be of grate help if i can get some light on it.

good question

why the rate in kg is equal to cbm,a higher cbm will carry lower weight goods ..

if you moving your shipment on sea freight you should have to equal KG to CBM because that good will stuff to container

it’s the best ever, thanks for sharing this precise information…thanks a ton or cbm

what would be the dimesions on 2 cubic meters
