explain which is more accurate: measuring to the nearest millimeter or to the nearest eighth of an inch
1 inch = 2.54 cm
1 inche = 25.4 mm
1/8 inch = 3.175 mm
Since it takes appr 3 mm to cover 1/8 inch
the mm would be the more accurate measurement,
e.g to be off by 1/8 of an inch is the same as being off by 3 mm
another way:
1 inch measured in 1/8 units takes 8 divisions of a ruler
1 inche measured in mm units takes 25 divisions on a ruler.

How do you round to the nearest millimetre tho...
Josh are you kidding. Use a micrometer.
To determine which measuring unit is more accurate, we need to compare the precision of measuring to the nearest millimeter and to the nearest eighth of an inch.
Measuring to the nearest millimeter provides a higher level of precision compared to measuring to the nearest eighth of an inch. Here's why:
1. Millimeter Measurement:
- A millimeter (mm) is a metric unit and is smaller than an inch.
- There are 10 millimeters in a centimeter and approximately 25.4 millimeters in an inch.
- As a result, measuring to the nearest millimeter allows for more precise measurements since the unit is smaller.
- For example, if you measure an object using a ruler marked in millimeters, you have the ability to estimate a measurement to the nearest 0.1 mm.
2. Eighth of an Inch Measurement:
- An eighth of an inch is a fractional unit of measurement and is larger than a millimeter.
- There are 8 eighths in an inch.
- Measuring to the nearest eighth of an inch introduces some limitations in terms of precision.
- For example, if you measure an object using a ruler marked in eighths of an inch, you can estimate a measurement to the nearest 1/8 inch, meaning you are approximating 0.125 inch increments.
Based on the above explanations, when measuring to the nearest millimeter, you have a smaller unit to work with, allowing for more precise measurements. In contrast, measuring to the nearest eighth of an inch limits the precision to larger increments.
Therefore, measuring to the nearest millimeter is generally considered more accurate than measuring to the nearest eighth of an inch.
