Don’t do much calculations in lb and oz, but I can read the charts: Latest addition of growth chard (0 - 36 mnth) is in lb and 16 oz in a lb.
Found this on the Internet:
The smallest unit of mass is ounces (oz).
One ounce weighs about the same as a slice of bread. It is very light.
The abbreviation for ounce is “oz”, because it came from the 15th century Italian word “onza”.
But be careful: “Ounce” and “Fluid Ounce” are different!
Ounce is mass
Fluid Ounce is volume ;-))
**
Here we talk about ounce as a mass.**
When you get lots of ounces you get a new label: The Pound
If you have 16 ounces, it can also be called a pound (lb).
1 pound = 16 ounces
The abbreviation is “lb”, because it came from the Latin word “libra”.
Typically, this is the unit that you use to measure your own weight.
Pounds are used to measure lots of things from people to food to animals.
**My conclusion of above: **The US SI is not divided in decimals but in oz. So within the calculations made, there should be a repair: 14.5 lb should be remade into: 14 lb 8 oz , most probably this error was embraced due to quick programming.
As a side thought, are three slices of bread on the weight of a child really important? Would this influence the statistics for government or insurance companies…………
