Chemistry and Physics Conventions: Constants, Sources and Sign Conventions
Constants and atomic data come from cited sources (NIST, IUPAC, CODATA) shown on the sheets. Conventions for rounding, the value of g, sign conventions, and significant figure mode are printed on every sheet. Teachers can choose the course level.
Constants and sources
Constants and atomic data come from cited sources (NIST, IUPAC, CODATA) shown on the sheets. Conventions (rounding, the value of g, sign conventions, significant figure mode) are printed on every sheet. Teachers can choose the course level (Chemistry, Honors, AP, IB) for chemistry and physics tools.
What is printed on every sheet
Every chemistry and physics sheet prints the conventions used, so a student or substitute teacher can see exactly how the numbers were calculated. This includes the value of g, the rounding mode, the sign convention, and the significant figure mode.
Frequently asked questions
Can I change the course level for chemistry and physics tools?
Yes. Chemistry and physics tools let you choose the course level: Chemistry, Honors, AP, or IB. The sheet adjusts the conventions and depth to match.
