Carat Weight Formula:
From: | To: |
The MM to Carat Weight Calculator estimates the carat weight of a diamond based on its physical dimensions (length, width, and depth). This formula is commonly used in the gemology and jewelry industry for diamond weight estimation.
The calculator uses the standard diamond carat weight formula:
Where:
Explanation: This formula provides an approximate carat weight based on the volume of the diamond, with 190 being the standard divisor for diamond density calculations.
Details: Accurate carat weight estimation is crucial for diamond valuation, jewelry design, insurance purposes, and gemological assessments. Carat weight is one of the 4Cs (Carat, Cut, Color, Clarity) that determine a diamond's value.
Tips: Enter all dimensions in millimeters. Use precise measurements for accurate results. All values must be positive numbers greater than zero.
Q1: How accurate is this calculation?
A: This formula provides a good estimate for standard diamond cuts. However, actual carat weight may vary based on cut precision, shape, and density variations.
Q2: Does this work for all gemstones?
A: No, this formula is specifically calibrated for diamonds. Other gemstones have different densities and require different conversion factors.
Q3: What is the standard conversion factor of 190 based on?
A: The factor 190 is derived from the average density of diamonds and is widely accepted in the gemological industry for carat weight estimation from dimensions.
Q4: How should I measure the dimensions?
A: Use calibrated gemological calipers for precise measurements. Measure to the nearest 0.01mm for best accuracy.
Q5: Can this be used for irregular shaped diamonds?
A: This formula works best for standard cuts (round, princess, oval, etc.). For irregular shapes, professional gemological assessment is recommended.
