Limits of accuracy.
Measurements are never exact numbers. No matter how good your measuring instrument
is, it cannot produce an infinite queue of decimals.
The number of decimals indicates how accurate a measurement is.
The length of an object can be indi

Limits of Accuracy
What are they?
Any measurement we make is rounded to
some degree of accuracy or other
Nearest metre
Nearest litre
The degree of rounding gives the possible
values of the measurement before rounding
For example
A lighthouse is 76m
