The Metre as a Metric: Canada's COVID-19 Conversion Kerfuffle.

Area of Science:

• Mathematics Education
• Science Communication

Background:

• The COVID-19 pandemic highlighted widespread inaccuracies in the application of the metric system in Canada.
• Social distancing signage frequently misrepresented metric units (e.g., 2 meters) and imperial units (e.g., 6 feet).

Purpose of the Study:

• To critically examine the prevalent disregard for the metric system in Canadian public spaces during the COVID-19 pandemic.
• To highlight the implications of this misrepresentation for mathematics education and public understanding of scientific units.

Main Methods:

• Observational analysis of social distancing signage and public health communications in Canada.
• Qualitative assessment of the accuracy of unit conversions and metric system representation.

Main Results:

• Significant inconsistencies were observed in the conversion and use of metric (meters) and imperial (feet) units on signage.
• Both private businesses and various levels of Canadian government demonstrated a lack of precision in metric system application.

Conclusions:

• The flippant treatment of the metric system in public messaging during a critical health crisis is a cause for concern for Canadian mathematics educators.
• There is a need for greater accuracy and consistency in the use of the metric system to support scientific literacy.
