1. What is Spring Rate Conversion?

Spring rate conversion is the process of converting a spring's rate from one measurement system to another. This is particularly important in metal springs where different industries or regions may use different units of measurement.

2. How Does the Calculator Work?

The calculator uses the spring rate conversion formula:

Where:

• \( K_{new} \) — New spring rate (units)
• \( K_{old} \) — Old spring rate (units)
• \( Factor \) — Conversion factor (dimensionless)

Explanation: The equation simply multiplies the original spring rate by a conversion factor to get the equivalent rate in different units.

3. Importance of Spring Rate Conversion

Details: Accurate spring rate conversion is crucial when working with international specifications, changing measurement systems, or comparing spring specifications from different sources.

4. Using the Calculator

Tips: Enter the original spring rate and the appropriate conversion factor. Common conversion factors include:

• N/mm to lb/in: 5.710
• lb/in to N/mm: 0.175
• kgf/mm to N/mm: 9.807

5. Frequently Asked Questions (FAQ)

Q1: What is spring rate?
A: Spring rate is the amount of force required to compress or extend a spring by a unit of length.

Q2: Why convert spring rates?
A: Different industries and countries use different units, so conversion is needed for accurate comparison and specification.

Q3: Are all conversion factors constant?
A: Yes, conversion factors between measurement systems are constant for linear springs.

Q4: Does material affect the conversion?
A: No, the conversion is purely mathematical, though material properties affect the original spring rate.

Q5: Can this be used for non-metal springs?
A: While the math is the same, this calculator is specifically designed for metal springs.
