Accurate Cargo Logistics
While she would likely poison my dinner or make a chubby “Rob Doll” for her voodoo pins if she knew I was writing this in a public forum, my wife is lousy at math. I mean lousy. This woman is a great teacher for our children; she is impossible to beat at Scrabble or Trivial Pursuit; she is at least three times smarter than I am… and, she has a panic attack if you mention “square root” or “divisible” or (God forbid) “numerator.” I tattle on her because I want all of you who suffer from Mathoplexy to know that you are not alone, and some very bright people out there are as terrified of mathematics as you are. For me, black mamba snakes defy all rational explanation and the smallest thought of one causes me to tremble and get under my desk. I digress.
If you want to excel in our industry, you must face your math phobia head-on. From perfect Customs entries, to accurate pricing/invoicing, to clean logical logistics, you better have a competence for numbers and calculations. So, job one is to summon the courage to ask for help. As adults, we are taught to feel foolish for not knowing everything under the sun. This is particularly true for language skills and mathematics. After all, we spent close to 20 years trundling off to school to learn this stuff. But, if you are not reasonably well prepared and confident with numbers, you will create a self-imposed ceiling for yourself. Don’t do that!
For those of you in between a panic attack and full “numerical” self- confidence, let’s summarize the fundamental math of our business:
- To get kilos from pounds, DIVIDE by 2.2046
- To get pounds from kilos, MULTIPLY by 2.2046
Ta da! That was easy as pie… now MEMORIZE it, already. This is a key building block.
Volume (Ocean Freight):
You usually get dimensions in inches. So, the typical scenario presents you with these calculations:
- Length (inches) X Height (inches) X Width (inches) X Number of Pieces = Volume Basis
- Volume Basis DIVIDED by 1728 = Cubic Feet
- Cubic Feet DIVIDED by 35.314 = Cubic Meters
If you have centimeters, you DIVIDE by 2.54 to get inches.
If you have millimeters (rare), you DIVIDE by 22.54 to get inches.
Volume (Air Freight):
- Volume Basis DIVIDED by 366 = Volume Kilograms
- Volume Basis DIVIDED by 166 = Volume Pounds
Note 1: It is essential with air calculations to understand that some carriers (primarily cartage companies for domestic pick-ups and deliveries) use their own chargeable basis. For example, one might charge based on a “volume pound factor of 250.” This means your cost and invoicing calculations would use 250 in place of the 166 above.
Abstract Math for Advanced Student
To me, the absolute key to good cargo math is the power of your imagination; that’s why I’m calling this “abstract” math. You need to be able to imagine cargo from a size and shape perspective and then imagine that cargo in its potential shipping conveyance (loose, containerized, consolidated, etc). When you can imagine these things, you can sketch the configurations necessary for making solid logistical choices and comparisons.
