### 2/5 — Litres to Gallons?

*2026-05-28, version 1.3*

Why not !

### 5/5 — Super useful

*2025-12-29, version 1.3*

Easy to use. Would appreciate negative units in the temps though.

### 1/5 — Missing conversation

*2024-11-25, version 1.3*

Not having basic money conversions is a big negative

### 4/5 — Conversions

*2023-07-25, version 1.3*

So simple to use, does everything most people would want. Would like to be able to use imperial measurements though.

### 1/5 — Manque le principal !

*2023-03-19, version 1.3*

La conversion de monnaie est absente or c’est l’une des principales utilisations !

### 4/5 — Currencies

*2023-03-19*

Please add currencies

### 3/5 — Appli très sympathique mais trop basique

*2023-02-26, version 1.3*

Appli simple, chouette et ergonomique mais trop basique dans les possibilités de conversion. Il manque pour mon usage les surfaces agricoles, hectare et autres, ainsi que les conversions numériques tel que les megibytes en megabytes par exemple.

### 3/5 — Ok

*2023-01-17, version 1.3*

Fine and simple. Doesn’t do compund eg stone and pounds or feet and inches

### 1/5 — Inaccurate!

*2022-11-26, version 1.3*

The developer needs to go back and review his formulas, because the calculations are WRONG!

### 5/5 — Converted!.

*2022-07-10, version 1.3*

Best converter I’ve ever used, everything you could ever want.
