In practice
Inches to metres combines two scales, so it is easy to be off by a power of ten. One inch is exactly 0.0254 m (2.54 cm), so 100 inches is 2.54 m and 36 inches (a yard) is 0.9144 m. It is used for screen and TV sizes, window and door openings, and product dimensions for international shipping. A good sanity check is that a metre is just under 40 inches (39.37), so if your answer for 80 inches is far from 2 metres you have probably shifted a decimal place.
