A unit converter changes a value from one measurement unit to another within the same category.
Temperature uses offset formulas, while most other categories convert through shared base units.
Choose the matching category
Length, weight, area, volume, data, and temperature use different conversion rules.
Watch rounded output
Everyday conversions are fine here, but legal, scientific, or industry work may need more precision.
result =target.fromBase(source.toBase(value))
Most categories convert through a shared base unit. Temperature uses dedicated formulas because Fahrenheit, Celsius, and Kelvin include offsets.
This page focuses on everyday conversions for product specs, labels, shipping, recipes, file sizes, layouts, and measurement cleanup.
Example
10 inches converts to 25.4 centimeters because 1 inch equals 2.54 centimeters.
Assumption
Most units convert through a shared base unit. Temperature is handled separately because it uses offsets.
Limitation
Displayed results may be rounded. Scientific, legal, and industry-specific unit variants may need dedicated references.
Mixing categories
Only convert within the same measurement category. Length, area, volume, mass, data, and temperature use different rules.
Confusing KB and KiB
KB is decimal and KiB is binary. File systems, cloud limits, and product specs may use different conventions.
Ignoring rounding
Displayed values are practical rounded results. Scientific, medical, legal, or engineering work may need stricter references.
Product specs
Convert dimensions, weights, and file sizes for listings or documentation.
Recipes and labels
Switch volume and weight units when cleaning up copied measurements.
Temperature checks
Convert Celsius, Fahrenheit, and Kelvin with the correct offset formulas.
Data sizes
Compare decimal KB/MB/GB and binary KiB/MiB/GiB values.
metric to imperial converter
Convert centimeters, meters, kilograms, liters, and similar metric values into familiar imperial units.
inches to cm
Move product dimensions, desk sizes, screen measurements, or label copy between inches and centimeters.
pounds to kg
Convert body weight, package weight, shipping notes, or product specs between pounds and kilograms.
KB and KiB data sizes
Compare decimal KB/MB/GB values with binary KiB/MiB/GiB conventions before publishing specs.
Can I convert inches to centimeters?
Yes. Choose Length, set From to Inches, and set To to Centimeters.
Can I convert pounds to kilograms?
Yes. Choose Weight, then convert Pounds to Kilograms or any other supported weight unit.
Does this support binary data units?
Yes. It includes KiB, MiB, and GiB alongside decimal KB, MB, and GB.
How are unit conversions handled?
Calculations are designed to run in the browser based on the current public implementation. Specialized engineering, legal, medical, or scientific work may need stricter references.
