XVert

XVert – Custom Unit Converter
Most unit converters give you the basics. XVert lets you build your own.
XVert comes loaded with essential conversions across length, weight, temperature, volume, speed, and more — but the real power is in the Formula Builder. Create custom formulas for any conversion that doesn't exist yet: fuel economy in obscure units, cooking ratios, workshop calculations, hobby-specific measurements. If you can express it as a formula, XVert can convert it.
