Tire Size Converter vs Screw Thread Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Tire Size Converter
Convert a metric tire size (width, aspect ratio, and wheel diameter) into overall tire diameter in inches. Use this when comparing tire sizes, checking fitment, or calculating speedometer error after a tire change.
- Answers
- Overall Tire Diameter (inches)
- Inputs
- Tire Width, Aspect Ratio, Wheel Diameter
Screw Thread Calculator
Compute the tensile load capacity of a metric screw thread based on nominal diameter, pitch, material strength, and safety factor. Use it when verifying bolt joint adequacy in structural or mechanical assemblies.
- Answers
- Safe Working Load (N)
- Inputs
- Nominal Diameter, Thread Pitch, Material Grade, Safety Factor
