RealisticPhysics UnitConverter provides clean runtime APIs, 97 conversion families, 1,632 supported units, and optional Unity Inspector integration for practical production workflows.
RealisticPhysics UnitConverter is built around practical Unity development. Use it for quick one-off conversions, structured runtime systems, custom editor tools, simulation values, imported data, gameplay balancing, or any workflow where values need to move between different unit systems without messy helper code.
A structured Unity conversion framework with organized APIs, clear namespaces, reusable conversion families, editor integration, settings-based configuration, and documentation for extending the system with new units or families.
Unity developers, technical artists, simulation developers, physics and gameplay programmers, tool developers, and teams that need clean, reliable unit conversion workflows inside Unity projects.
The package includes a broad conversion library covering common Unity, scientific, engineering, electrical, digital, physical, and utility workflows. Each family has its own unit enum and converter class, keeping conversions organized and helping prevent invalid cross-family mistakes.
Choose the style that fits your codebase — explicit converters, fluent extensions, or direct unit methods.
Use family-based converter classes when you want explicit, readable conversion calls.
using RealisticPhysics.UnitConversion.Length;
double centimeters = UnitConverterLength.Convert(
1.5,
UnitConverterLengthUnit.Meter,
UnitConverterLengthUnit.Centimeter);Readable numeric workflows. Supports double, float, decimal, and common integral types.
using RealisticPhysics.UnitConversion.Length;
double value = 1.5;
double centimeters = value.Convert(
UnitConverterLengthUnit.Meter,
UnitConverterLengthUnit.Centimeter);Highly explicit method names with namespace-based auto-complete.
using RealisticPhysics.UnitConversion.Length.Metric;
double centimeters =
UnitConverterMetricLength.MeterToCentimeter(1.5);Each conversion family follows a canonical base-unit conversion pattern. Values convert into the family base unit and then out to the requested unit. This keeps behavior consistent across API styles and makes the system easier to understand, maintain, test, and extend.
Incompatible conversions are prevented by separate enums and converter classes — length uses length units, power uses power units, mass uses mass units, and so on.
UnitConverter includes optional Unity editor inspector overrides. Unity continues to store native values normally, while UnitConverter displays and edits converted values in the Inspector.
Edit Position Y to 100 cm → Unity stores 1.0 m. Preferred position unit is set in UnitConverter settings.
Mass conversions use your preferred Rigidbody mass unit from settings (e.g. kilogram, pound, gram).
Collider dimensions convert with your preferred length unit while Unity keeps native meter-based size values.
Change radius to 50 cm in the Inspector → Unity stores 0.5 m.
Radius and height both respect the collider length unit configured in UnitConverter settings.
Useful for character-scale tuning without mentally converting meters and centimeters.
Clip planes can be shown in centimeters, millimeters, feet, or other length units from settings.
Set preferred Light range unit in settings (e.g. meter, centimeter, foot).
Audio falloff distances use your preferred audio distance unit from the settings asset.
Inspector overrides and display preferences are controlled through a dedicated UnitConverter settings asset.

Import only the families or direct unit systems you need. US and UK Imperial volume units are separated because some unit names are shared but values differ.
