Article C2.5
Precision of Numerical Values
Chapter: ARTICLE C2: CONVENTIONS AND FUNDAMENTAL DIMENSIONS
In Simple Terms
When F1 regulations set numerical limits (like maximum weights or minimum dimensions), those exact numbers are the boundaries—no rounding or negotiation allowed. Whether a rule says 798kg or 798.5kg, teams must meet that precise specification.
- Numerical limits in regulations are absolute and cannot be rounded
- Both maximum and minimum values are treated with equal precision
- Applies regardless of how many decimal places are specified
- Teams cannot argue they were 'close enough' to a limit
Official FIA Text
Any numerical values specified in these Regulations as limits (maxima or minima), will be considered to be the limits regardless of the decimals quoted.
