Make measurements in tenths by measuring in inches, then dividing the result by 1.2. Alternatively, use an engineering tape measure or ruler that is marked in tenths.
Tenths are a commonly used unit of measurement in construction and engineering, equivalent to one-tenth of a foot. Engineers and surveyors often measure in tenths rather than traditional feet and inches to make calculations easier. You can multiply and divide measurements in tenths without the need to convert between feet and inches, which is useful when calculating areas. To convert back from tenths to feet and inches, divide by 12 for the length in feet, then multiply the remainder by 1.2 for the inches.
