Perform each unit conversion. a. 1.4 in to mm

검증된 단계별 안내

Step 1: Identify the conversion factor. The conversion factor between inches and millimeters is 1 inch = 25.4 mm.

Step 2: Write down the given value, which is 1.4 inches.

Step 3: Multiply the given value by the conversion factor. This is done by setting up the conversion so that the unit you want to convert from (in this case, inches) will cancel out. So, you should multiply 1.4 inches by 25.4 mm/1 inch.

Step 4: Perform the multiplication. The inches unit will cancel out, leaving you with the result in millimeters.

Step 5: Write down your final answer, making sure to include the correct units (mm).
