Frequently asked questions
How accurate are these conversions?
Conversions use standard, widely accepted conversion factors (e.g., 1 inch = 2.54 cm exactly). Results are rounded for readability but calculated at full precision.
Why is temperature handled differently from other categories?
Unlike length or mass, temperature scales don't share a common zero point, so conversion requires a formula rather than a simple multiplication factor — Celsius, Fahrenheit and Kelvin each start counting from a different physical reference point.
Can I convert between metric and imperial units?
Yes — each category includes both metric (cm, kg, mL) and imperial/US customary (in, lb, gal) units in the same dropdown, so you can convert freely between systems.
Does this cover units for chemistry or physics specifically?
This converter covers general-purpose length, mass, volume, temperature, time and speed units common across most introductory science and math courses, not specialized scientific units like moles or joules.
