The wavelength converter is a free online tool that helps you convert between physics units quickly and accurately. It supports 5 units including Nanometer (nm), Angstrom (Å), Micrometer (μm), Meter (m), Picometer (pm). The core conversion formula is: 1 nm = 10 Å = 0.001 μm. For example, 1 Nanometer equals approximately 10 Angstrom. Conversely, 1 Angstrom equals approximately 0.1 Nanometer. Common conversions: 5 nm = 50 Å, 10 nm = 100 Å, 25 nm = 250 Å, 50 nm = 500 Å, 100 nm = 1,000 Å. This converter is useful for students, engineers, scientists, and professionals who need accurate physics unit conversions. Whether you are working on homework, technical specifications, research data, or everyday measurements, this tool provides instant, reliable results. All conversions are calculated relative to a single base unit for consistency and precision across all supported units. Visible light wavelengths range from 380-700 nm. X-rays have wavelengths of 0.01-10 nm.
