When to use this
- You already know the source and target units and need the value converted.
- You need to compare units inside the same physical quantity, such as pressure, flow, or density.
Unit Converter
Unit Converter
Convert scientific and lab units for pressure, flow rate, conductivity, resistivity, density, viscosity, spectroscopy, energy, and more in one mobile-friendly tool. It fits the moments when a lab note, spec sheet, or report needs consistent notation fast.
Converted value—
Switch between pressure, flow rate, conductivity, density, viscosity, spectroscopy, and other scientific or lab units in one place.

Formula / focus
Compare pressure, flow rate, density, viscosity, conductivity, and spectroscopy units in one flow when a lab note, spec sheet, or report needs consistent notation.

Decision Check Before Calculating
How it differs from nearby calculators
Conversion pages change units, not the underlying question. Use scientific or basic calculators for follow-up formulas after the unit is correct.
Common input mistakes
- Converting between units that do not describe the same quantity.
- Forgetting that temperature and spectroscopy use formulas rather than simple scale factors.
How to read the result
- Read both the source unit and target unit with the value.
- If the unit category feels wrong, switch category before using the number elsewhere.
Next action
- Copy the converted value into the formula calculator only after the unit label is correct.
- Check the examples for the closest real-world unit pair.

Overview
Use this all-in-one converter when scientific or engineering work needs consistent units across notes, specs, or reports.
In addition to core units such as length and volume, it covers pressure, flow rate, conductivity, resistivity, density, viscosity, surface tension, and spectroscopy in the same flow.
How To Use It
- Choose the category.
- Select the source and target units.
- Enter the value, read the converted result, and switch categories if your workflow needs another measurement family.
FAQ
Q. Can I use it offline?
Yes. With cached assets and PWA support, return visits stay practical even with limited connectivity.
Q. Which unit types are included?
It covers core measurement units plus time, pressure, flow rate, force, power, frequency, electrical units, conductivity, resistivity, magnetic field, amount, concentration, mass concentration, density, viscosity, kinematic viscosity, surface tension, and spectroscopy.
Q. Does it support cm³, joules, density units, molar concentration, conductivity, flow rate, and wavenumbers?
Yes. It includes cm³ and dm³, J and eV, density units such as g/cm³, concentration units such as mol/L, conductivity units such as mS/cm, flow-rate units such as mL/min, and spectroscopy units such as cm⁻¹.
Q. How does spectroscopy conversion work?
The spectroscopy category converts between nm, µm, Å, cm⁻¹, THz, and eV by using photon relationships instead of a simple scale factor.
Q. Does it support temperature conversion?
Yes. Temperature uses dedicated formulas rather than simple scaling.
Example Inputs
1 atm → kPa
1 atm → 101.325 kPa
Useful when a spec sheet uses atm but the report needs kPa.
1 mS/cm → S/m
1 mS/cm → 0.1 S/m
Useful for matching conductivity values to the notation used in a paper or material sheet.
1 cSt → mm²/s
1 cSt → 1 mm²/s
Useful when a viscosity data sheet and your notes use different labels for the same value.
500 nm → cm⁻¹
500 nm → 20000 cm⁻¹
Useful for moving between wavelength and wavenumber in spectroscopy work.
