# Study guide – Fractional and Millesimal Inch

`Guide to interact with the pages of the topic 'inch, reading and transformation'`

The purpose of this page is to guide the studies and to serve as an index for most of the pages that deal with the topics: ‘fractional inch’ and ‘thousandth inch’ from the Prof. Eduardo Stefanelli webpage. Select in the lists below the subject of your interest or just follow the proposed guide. To return to this page, click in the link ‘Inch’ from ‘Metrology’ menu.

## Fractional Inch

1) Start your studies understanding the fractions and the fractional inch directly in the ruler below;
Use of measures in fractional inch – understanding and applying

2) Now, practice your measurement ability with a ruler graduated in fractional inch;

Ruler or virtual line gauge – simulator of use and interpretation in fractional inch

3) Evaluate your performance on this self assessment program;

self-assessment : line gauge in fractional inch (ruler)

4) Comprehend the method to convert measures in millimeter to inch and vice versa;

Conversion of millimeter, fractional and thousandth inch – interactive conversor

5) Now, comprehend the fractional inch and its measurement process with the use of vernier caliper;
Vernier scale or nonius: simulator of reading and interpretation in fractional inch – 1/128″

6) Practice your ability to use the vernier caliper in fractional inch;

Simulator of use, reading and interpretation of vernier caliper in fractional inch – 1/128″

7) Tips and tricks that can be useful;
Use of vernier caliper in fractional inch – comprehending and measuring

9) Now, practice the ability to use the digital caliper in fractional inch;

Simulator of use of digital caliper in fractional inch – 1/128″

10) Practice your ablility to use the vernier dial caliper in fractional inch

## Tenth/thousandth inch

1) Measurement in decimal inch is very similar to the same process in millimeter. This way, we suggest you interact with the page: escale or virtual line gauge – simulator of use and interpretation in millimeter before you go ahead.

2) Practice the ability of measuring with a line gauge, also known as scale in tenth inch;

Use of measures in tenth inch – comprehending and applying

3) Evaluate your performance on this self-assessment program.

Self assessement : line gauge in tenth inch (ruler)

4) Comprehend the method to convert measures in millimeter to thousandth inch and vice versa with the conversor that you already know;

Conversion of millimeter, fractional and thousandth inch – interactive conversor

5) See how simple it is to measure in thousandth inch with the use of vernier;

Vernier scale or nonius: simulator of reading and iterpretation inthousandth inch

6) Now, practice your ability to use the vernier caliper in thousandth inch;

Simulator of use, reading and interpretation of vernier caliper in thousandth inch

7) Now, practice your ability to use the digital caliper in thousandth inch;

Simulator of use of digital caliper in thousandth inch

8) Practice and know the ability to use the dial indicator in thousandth inch;

Simulator of dial indicator in thousandth inch (1.000″)

9) Practice your ability to use the dial caliper in thousandth inch;
