Millimeters to Micrometers Converter
Scientific converter for mm to μm (microns). Supports scientific notation, high-precision floating point arithmetic, and swap functionality for lab and engineering use.
About
In microscopy and semiconductor manufacturing, dimensions shift from the visible millimeter scale to the microscopic micrometer (micron) scale. A single millimeter contains one thousand micrometers. Precision at this level is non-negotiable; a deviation of a few microns can ruin a CNC machining job or invalidate a biological sample analysis.
This tool bridges the gap between macro and micro measurements. It is explicitly designed to handle scientific notation, allowing direct pasting of data from laboratory software. The internal logic uses high-precision arithmetic to ensure that extremely small fractions are converted without floating-point truncation errors.
Formulas
The prefix "milli-" denotes 10-3 meters, while "micro-" denotes 10-6 meters. The factor between them is exactly 1000.
Lμm = Lmm × 1000
Conversely:
Lmm = Lμm ÷ 1000
