Hi everyone,

I’m looking to confirm whether the following unit conversions are still accurate when working with FMOD Studio 2.03+ and Unreal Engine 5.6, using Unreal’s default unit settings:

- 1 FMOD unit = 1 meter

- 1 Unreal unit = 1 centimeter

- Therefore, 1 FMOD meter = 100 Unreal units

Is this correct?

Thanks in advance for your help!

Romain

Hi Romain,

Your conversion is indeed correct.

In the FMOD Unreal integration, world positions are automatically converted from Unreal’s centimeters to FMOD’s meters before being passed to FMOD.

For reference:

- [FMOD\_VECTOR\_SCALE\_DEFAULT](https://fmod.com/docs/2.03/unreal/api-reference-common.html#fmod_vector_scale_default) : Shows the default scale factor of `0.01f`, meaning 1 cm in Unreal = 0.01 m in FMOD.
- [FMODUtils::ConvertWorldVector](https://fmod.com/docs/2.03/unreal/api-reference-common.html#fmodutils_convertworldvector) : The helper function used to apply this conversion in the integration.

Hope this helps!
