Rounding is when you take a decimal or fraction and make it the closest whole number. If the number you are rounding is five or higher round up and if it's four or below round down. For instance, 7.2 rounds down to 7, 6.8 rounds up to 7.
Rounding to the nearest hundredth is more accurate.

By rounding each of the numbers involved.
It is the accuracy in the estimate of the constant or the effect of rounding.
You can calculate 3444 times 670 without rounding or you can estimate it WITH rounding. But you cannot estimate it without rounding.
An estimate is an educated guess based on prior knowledge. Rounding off is knowing the exact value but rounding it to the nearest whole number.
Rounding to the nearest hundredth is more accurate.

rounding
An Estimate is basically a guess. Rounding is when you have an answer and you shorten the answer to a given number of digits. eg $27482 would round to $27500 to the nearest hundred dollars.
An estimate of 348 would typically be rounded to the nearest ten, hundred, or thousand depending on the level of precision needed. Rounding to the nearest ten would give an estimate of 350, rounding to the nearest hundred would give an estimate of 300, and rounding to the nearest thousand would give an estimate of 0.5. The choice of which rounding method to use would depend on the context in which the estimate is being used.
By rounding off.
