The way I really understand it, is that its estimating by the highest place value, not a very close estimation, but still around the number.

A reasonable estimate will give an indication of the order of magnitude of the number. The order of magnitude is determined by the decimal point and so knowing the order can help in placing it.
The magnitude estimate for 12.2 multiplied by 1.56 is approximately 19.03.

OOM (Order of magnitude) estimate
It is a million.
It is tens of thousands.
Tens of thousands.
Estimating help determine the order of magnitude of the answer. It is, therefore, a simple matter to place the decimal point is such a way that the order of magnitude of the calculated answer matches that of the estimate.
Apparently a magnitude estimate is just a estimate just closer to the actual answer.
An order-of-magnitude estimate is a rough calculation used to quickly determine the approximate size or scale of a value. It involves rounding numbers to the nearest power of 10 to simplify calculations and get a quick understanding of the scale of a quantity. It is a useful technique for making quick assessments or approximations without the need for precise calculations.
