Chapter 1, Problem 94a
Perform each unit conversion. a. 1.4 in to mm
Verified step by step guidance1
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).
