Benefits

Instant, free, and requires no signup or installation; works from any device with a browser; uses the standard, verifiable conversion factor rather than an approximation.

Limitations

Calculations use standard JavaScript floating-point arithmetic, so very large or very high-precision inputs may show minor rounding differences; the tool assumes the standard modern definition of each unit, not historical or region-specific variants.
