Unit Converter
Converting between imperial and metric units for length, weight, pressure, temperature, torque, and speed.
Overview
The Unit Converter supports six categories of conversions commonly needed in manufacturing: Length (in, mm, cm, m, ft), Weight (lb, kg, oz, g), Pressure (PSI, bar, MPa, kPa), Temperature (°F, °C, K), Torque (ft-lb, N·m, in-lb), and Speed (SFM, m/min, ft/s, m/s). Select a category, choose your 'from' and 'to' units, and type a value — the result updates instantly.
Swap Button
Click the swap arrow between the 'from' and 'to' fields to reverse the conversion direction. The current result becomes the new input value, so you can quickly toggle back and forth without retyping.
Precision
Results are displayed to 8 significant figures with trailing zeros removed. This provides sufficient precision for most machining tolerances (which typically require 4–6 decimal places in inches or 2–3 in millimeters).
Free Access
The Unit Converter is available to all users, including those without an active subscription. No upgrade is required to use this tool.
