Metric and Imperial Units in Construction Calculations
Avoid conversion errors when drawings, tools and packages use different measurement systems.
Metric and Imperial Units in Construction Calculations
Choose one working system for each calculation and convert at the beginning, not halfway through a formula. Length, area and volume need different conversion factors. A linear conversion must be squared for area and cubed for volume. Keep the original measurement beside the converted value for checking.
Worked example
1 ft = 0.3048 m; 1 in = 0.0254 m; 1 yd³ = 0.764554857984 m³
