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.

Relative permeability

Optional number input.

Convert H (A/m or oersted) to B (tesla or gauss) using B = μ₀μᵣH. A material's relative permeability is required when crossing dimensions; unit-only conversions do not use it. 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.

• Absorbed Dose Converter

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

• Equivalent Dose Converter

  Convert radiation equivalent dose between sieverts and rem; do not use these units as absorbed-dose grays.

• Torque Converter

  Convert torque between newton-metres, pound-force feet, and kilogram-force metres. Torque has the dimensions of energy but is not an energy quantity.
