The quote handoff carries your inputs and assumptions. Only an explicit base cost is suggested as a quote cost; prices, rates and measurements remain planning notes.
How it works
1 inch = 25.4 mm exactly; 1 foot = 304.8 mm; 1 cm = 10 mm; 1 m = 1,000 mm. Convert the source to millimeters, then divide by the destination factor.
- This converts lengths only. Areas and volumes require squared and cubed conversion factors. Signed values are allowed for offsets.
