Log Calculator

Common Log Calculator Log10 Calculator

Common logarithm calculator finds the logarithm function result in base 10. Calculate log base 10 of a number.

Common Log Calculator log10
log(x) = y

log10(x) = y is equivalent to x = 10y

Common log is also written without the base 10,
log10(x) = log(x)

x: is real number, x>0

Common Logarithm Examples

Using logarithm of a product identity to find common log of 120:

log(120) = log(100 × 1.2)
log(120) = log(100) +  log(1.2)
log(120) = 2 + 079181246 = 2.079181246

Using logarithm of a power identity to find common log of 106:

log(106) = 6 × log(10)
log(106) = 6 × 1 = 6
