What is the difference between weight and mass?

Mass is the amount of matter in an object (measured in kg or grams), while weight is the force gravity exerts on that mass (measured in Newtons). In everyday use, we often say "weight" when we mean "mass." On Earth, 1kg mass = 9.8 Newtons weight. Mass stays constant; weight changes with gravity.

How do I calculate shipping costs based on weight?

Most carriers charge by weight brackets. Example: 0-1kg = $10, 1-2kg = $15, etc. Some use dimensional weight (length×width×height÷5000 for cm, ÷139 for inches). Use the higher of actual weight or dimensional weight. International shipping typically uses kilograms regardless of origin country.

What are troy ounces and how do they differ from regular ounces?

1 troy ounce (precious metals) = 31.1035g. 1 regular ounce (avoirdupois) = 28.3495g. Troy ounces are about 10% heavier. Used for gold, silver, platinum. 1 troy pound = 12 troy ounces (vs 16 regular ounces in a pound). Always specify which type when dealing with precious metals.

What weight measurements are used in medicine and pharmacy?

Medicine uses metric: milligrams (mg), grams (g), kilograms (kg). 1g = 1000mg, 1kg = 1000g. Body weight in kg for dosage calculations. Never guess conversions for medications - use exact values. Some older references may use grains (1 grain = 64.8mg), but this is largely obsolete.

How do I track body weight changes across different scales?

Use the same scale consistently, at the same time daily (preferably morning, after bathroom, before eating). Different scales may show different numbers due to calibration. Focus on trends over time rather than daily fluctuations. Convert between kg and lbs if needed, but stick to one unit for tracking.

What are carats and how do they relate to other weight units?

1 carat = 200mg = 0.2g. Used for gemstones and pearls. Not to be confused with karat (gold purity). Example: 5-carat diamond = 1g. For jewelry, weights are typically given in carats for stones and grams for total piece weight. Precision is critical - small differences significantly affect value.
