Select category: Click a category tab (Mass, Volume, Concentration, Length, Temperature, Pressure, or Time) to switch the converter.
Enter value: Type any numeric value in the input field. The conversion table updates instantly as you type.
Change input unit: Select your input unit from the dropdown. All output values in the table update automatically.
About SI Units in the Laboratory
The International System of Units (SI) is the modern standardized metric system used in science worldwide. Using consistent SI units in lab work ensures accurate communication, reproducibility, and safety.
kilo (k) = 10³ = 1,000
milli (m) = 10⁻³ = 0.001
micro (µ) = 10⁻⁶ = 0.000001
nano (n) = 10⁻⁹ = 0.000000001
pico (p) = 10⁻¹² = 10⁻¹²
femto (f) = 10⁻¹⁵ = 10⁻¹⁵
// e.g. 1 µg = 10⁻⁶ g = 0.000001 g
Temperature in Lab Work
Celsius (°C) is used for most lab work. Kelvin (K) is used in thermodynamic calculations. Key reference points: 0°C = 273.15 K (water freezes), 37°C = 98.6°F (body/incubator temperature), 100°C = 373.15 K (water boils at sea level).
Concentration Units
Molar (M = mol/L) is the standard SI concentration unit. In molecular biology, µM, nM, and pM are common for small molecules and antibodies. mg/mL and µg/mL are used for proteins and antibiotics where molecular weight may be unknown.
