## How to add or Subtract Feet & Inches

Adding or subtracting lengths in feet and also inches can seem complicated, but it’s actually really basic if you monitor a couple of simple steps. It’s even much easier to include or subtract length measurements making use of a calculator choose the one above, but follow this easy actions to learn just how to execute it yourself.

### Step One: convert Feet and Inches come Decimal

The first thing come do as soon as adding, subtraction, or doing other math through inches, feet, and other measurements is to convert all the measurements into a usual unit that measure.

Start through converting customs fractions into decimal. Then transform feet, centimeters, and millimeters come inches.

Convert customs fractions come decimal by separating the bottom half of the fraction by the bottom fifty percent on a calculator. If over there is a whole number, include it to the decimal value after converting.

You can also use an inch portion calculator come quickly uncover the decimal worth for an inch fraction.

For example:3/8 = 3 ÷ 8 = .375 inches

Convert feet come inches by multiply the number of feet by 12, because there are 12 inches in a foot. Making use of a feet to inches conversion calculator also simplifies this step.

For example:3 feet = 3 × 12 = 36 inches

Try ours other size conversion calculators to convert other units to decimal inches.

### Step Two: add or Subtract the converted Values

With all measurements in an inch decimal form, add or subtract all measurements as you typically would, using a calculator together needed. The final result will be the size in inches; girlfriend can transform the result to any other unit at this point.

To refer the sum or distinction value in feet, just multiply by 12.

The following charts leveling the procedure of including and individually fractional inch values together and also might be much faster than utilizing a calculator.

## How to multiply or divide Feet & Inches

The actions to main point or divide feet and inches are comparable to the measures for adding and individually above.

### Step One: convert Feet and Inches come Decimal

The very first step in multiply or splitting is to convert the length measurements come a decimal value. If the size measurements space in feet and also inches, it can be most basic to transform to inches.

### Step Two: main point or Divide

With the size value convert to a decimal, it’s now feasible to multiply or divide as with you would with any decimal number. For example, if her inch value is 1.25 and you have to multiply through 2, merely multiply making use of 1.25 × 2 = 2.5.

The following charts do multiplying or separating fractional inch values much easier.
