Use this converter when the source value, representation, or measurement unit is known and you need the equivalent value in a supported target form without changing its underlying meaning.

Value

Required number input.

From unit

Required string input.

To unit

Required string input.

Convert pressure or mechanical stress among pascals, bars, atmospheres, torr, and pounds per square inch. Inputs represent absolute magnitudes, not gauge offsets. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Converted value

The resulting converted value returned as a number.

Unit

The resulting unit returned as a string.

• A conversion is only valid when the input convention is identified correctly. Unit systems, character encodings, byte order, color profiles, reference conditions, rounding, and calendar or time-zone rules can make superficially similar values non-equivalent.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Keep the original value and its unit or encoding alongside the result. For interchange, also validate the output against the receiving format, standard, color profile, or reference conditions.

• Vacuum Pressure Converter

  Convert absolute vacuum pressure among pascals, torr, millibar and atmospheres. Zero denotes ideal vacuum; this tool does not interpret negative gauge pressure.

• Power Converter

  Convert power among watts, metric and mechanical horsepower, and refrigeration tons; refrigeration ton means 12,000 BTU per hour.

• Absorbed Dose Converter

  Convert absorbed radiation dose between grays and rads; this is energy deposited per unit mass, not equivalent dose.
