F# units of measure catch mismatched time, length, and quantity units at compile time with zero runtime overhead.
F# Units of Measure attach compile-time dimension metadata to numeric types, preventing unit mismatches before runtime.
F# Units of Measure annotate numeric types with dimensions like metres and seconds, turning unit mismatches into compile-time errors. A projectile calculator shows how velocity, time and distance stay typed end-to-end.
F# units of measure attach compile-time physical dimensions to numeric types, turning silent unit-mismatch bugs into compiler errors. See a kinetic-energy example, understand runtime erasure, and adopt them on API boundaries.
Learn how F# Units of Measure catch unit mismatches at compile time, erase to plain floats at runtime, and integrate with existing .NET code.
F#’s Units of Measure let you attach dimensional units to numeric values, catching mistakes like adding meters to seconds at compile time. This post walks through defining units, using them in calculations, and highlights IDE support, trade‑offs, and a quick checklist.
Learn how F#'s Units of Measure let the compiler catch accidental mixes of meters, feet, and other units before your code runs.
Learn how F# units of measure provide compile‑time dimensional analysis, preventing unit mismatches before runtime with a worked example and practical verification steps.
Learn how F# Units of Measure add compile‑time dimensional safety to numeric code, see a meter‑to‑feet conversion example, and understand the trade‑offs when interfacing with raw .NET APIs.
