About these measurements
Length measures the distance between two points.
The base reference used here is the meter. One micrometer is 0.000001 base units; one inch is 0.0254 base units.
Important distinctions
International feet and inches are used. Survey feet are not included.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
