# CONVENTIONS

Note: This page is intended to list usage conventions to conform to on the other pages. Feel free to edit pages to conform to these standards. If you disagree with a standard here please generate discussion.

GENERAL RULES

- Units: every data must be expressed in SI (System International) { e.g. xxx.xx [m] } ; as the majority of ShroudScience members are Americans the following forms are accepted:
- measurement: xxx.xx [m] (yyy.yy [ft]), (SI and American units) => preferred
example: 1.07 m (3.5 ft)
- measurement: xxx.xx [m] (SI units) => accepted
example: 1.07 m
- measurement: yyy.yy [ft], (xxx.xx [m]), (American and SI units) => tolerated
example: 3.5 ft (1.07 m).
Note: every data should be expressed with its own uncertainty value and if this uncertainty is not reported (tolerated but not preferred), the numerical value is intended as expressed by means with the implicit (implied) uncertainty (this means that the last significant digit of the value is uncertain). Therefore if a value is converted in other units, a congruent number of significant digit MUST be taken.
Example: Amarican measurement 3.5 ft. The uncertainty is implicit and it means that the value 3.5 is in the range between 3.45 and 3.55. The conversion factor ft=>m is 0.3048 so 3.5x0.3048=1.0668 m that it is WRONG because this result has too much significant digits; 1.07 m is right.

- Capital letters: the first capital letter is used if we are speaking of a particular "Object" but the normal wording is used if we are speaking of a common "object". For example we can study the "Shroud" (TS) using a "shroud" for our experiments.

- Spectrum of Certitude: as the human knowledge is limited, the Science is in continuous development and therefore there are few statements that are 100% certain. It is frequently useful to assign a degree of certitude to some statements following this scheme in which numeric scores from 0 to 6 are assigned:
CERTAINLY FALSE 0, PROBABLY WRONG 1, DOUBTFUL 2, CONTESTED 3, PROBABLE 4, HIGHLY PROBABLE 5, CERTAIN 6.

- Reference to a grid: when reference to some details of the Shroud must be done, the reference grids of both frontal and back surfaces are shown in this page. They are also shown side by side in vertical format here.
