Length Unit Converter
Instantly convert between mm, in, and other Length units — accurate, free, and built for water treatment engineering work.
Quick Reference Table
| Unit | Converted to m | m converted to unit |
|---|---|---|
| mm | 1 mm = 0.001 m | 1 m = 1000 mm |
| cm | 1 cm = 0.01 m | 1 m = 100 cm |
| km | 1 km = 1000 m | 1 m = 0.001 km |
| in | 1 in = 0.0254 m | 1 m = 39.3701 in |
| ft | 1 ft = 0.3048 m | 1 m = 3.2808 ft |
Engineering Context
Membrane element diameters (4", 8", 16"), pipe nominal sizes, and vessel dimensions are specified in inches across almost the entire global membrane industry regardless of a plant's home unit system — this converter is built around that mixed-unit reality.

DCS vs. PLC in Water Treatment: Why Continuous Chemistry and Discrete Logic Need Different Control Architectures
A distributed control system and a programmable logic controller can both open the same valve, but they were built on opposite assumptions about what a plant is. Picking the wrong one for a zero-liquid-discharge evaporator or a scattered pump-station network doesn't show up on day one — it shows up years later, as downtime.
Read ArticleOversized Process Equipment in Industrial Water Treatment: Why Safety Margins Become Hidden Life-Cycle Costs
Stacked safety factors on pumps, blowers, membranes, and tanks don't just raise the purchase price — they push equipment out of its efficient operating window for years. A life-cycle model built on a real MBR retrofit shows a phased, right-sized design beating a one-time oversized build by roughly 10%, even when the deferred expansion eventually happens.
Read ArticleProduced Water Treatment: Why Direct Lithium Extraction Turns Zero Liquid Discharge From a Cost Center Into a Profit Center
Oilfield produced water has historically been a disposal problem solved by deep-well injection. As injection wells fill up and induced-seismicity restrictions tighten, the same brine is increasingly being read as a lithium ore body — but only if pretreatment is aggressive enough to protect an extraction bed that has zero tolerance for the oil and silica this water is full of.
