20 °C = 68 °F = 293.15 K.
Formula & detailed explanation
Values below absolute zero are rejected. Kelvin has no degree symbol.
Calculations use decimal arithmetic with 40 significant digits internally. Choose 0–8 decimal places for the displayed result. Trailing zeros are omitted. Rounding affects only the displayed and copied result; very small values may round to zero. Accepted inputs have up to 100 characters and magnitudes from 10⁻¹⁰⁰ to 10¹⁰⁰, plus zero.
