Common Questions

Frequently Asked Questions

Everything you need to know about using Ideal Body Weight Calculator safely, accurately, and privately.

How accurate is the Ideal Body Weight Calculator?
The Ideal Body Weight Calculator utilizes standard clinical equations recognized by the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). While it provides precise mathematical estimations for body metrics, metabolic rates, and pediatric percentiles, it should not replace individual clinical assessment by a qualified healthcare physician.
Is my personal health data saved on LoomFree?
No. All calculations run 100% client-side in your web browser memory. Your age, height, weight, and health metrics are never transmitted to our servers or stored in any database.
Does this calculator support both Metric and Imperial units?
Yes. You can toggle seamlessly between Metric units (kilograms, centimeters, liters) and Imperial units (pounds, feet, inches, fluid ounces) at any time with automatic value conversion.
How frequently should I track and calculate these metrics?
For weight management and wellness tracking, measuring weekly or monthly under consistent conditions (such as first thing in the morning) yields the most reliable trend analysis.
Can I export or print my calculation results?
Yes. You can copy summary metrics, export your results as a CSV file, or use your browser's Print feature (Ctrl+P / Cmd+P) to save a clean, formatted PDF report.
