What is a microjoule?

A microjoule (µJ) is one millionth of a joule and represents very small energy amounts common in laser pulse and microelectronics measurements.

Why convert microjoules to calorie (th)?

This conversion is useful for relating small energy quantities to older thermochemical units found in historical heat and calorimetry data.

Is calorie (th) still used in modern energy measurements?

The thermochemical calorie is largely replaced by joules but remains relevant for legacy data and older scientific literature.

Ideal for interpreting older heat and specific heat data in terms of legacy thermochemical units.
Provides examples for straightforward application of the conversion formula.

Examples

10 µJ equals 0.000002390057 cal (th) by multiplying 10 by 2.3900573613767e-7.
1,000 µJ equals 0.0002390057 cal (th) as calculated by multiplying 1,000 by 2.3900573613767e-7.

Common Use Cases

Measuring pulse energy in ultrafast and fiber lasers where energies range from nanojoules to microjoules.
Determining energy stored in small capacitors and micro-scale sensors in microelectronics.
Interpreting heat and specific heat capacity data in older literature and historical thermochemical tables.
Bridging modern micro-scale energy research with legacy thermochemical measurements.

Tips & Best Practices

Use this converter primarily for legacy data interpretation as calorie (th) is largely replaced by joules now.
Pay attention to the very small values involved and consider potential rounding effects in precise applications.
Verify your input units carefully to ensure correct and meaningful results.
Refer to provided examples to understand the correct usage of the conversion formula.

Limitations

The calorie (th) unit is mostly obsolete and preferred only for historical or legacy data contexts.
Conversion involves extremely small magnitudes which may be sensitive to rounding and precision errors.
The joule is the recommended standard for energy in modern scientific work, limiting this tool’s use.
