Dynes to Nanonewtons: 1 dyn equals 10000 nN. To convert dynes to nanonewtons, multiply by 10000 (nN = dyn × 10,000). For example, 10 dyn = 100000 nN.
How to Convert Dynes to Nanonewtons
To convert from dynes to nanonewtons, multiply the value by 10000. The conversion is linear, meaning doubling the input doubles the output.
Conversion Formula
- Dynes to Nanonewtons:
nN = dyn × 10,000 - Nanonewtons to Dynes:
dyn = nN ÷ 10,000

Understanding the Units
What is a Dyne?
A dyne equals exactly 10⁻⁵ newtons — the CGS unit of force, defined as the force needed to accelerate one gram by one centimeter per second squared.
Common contexts: surface tension, older physics texts.
What is a Nanonewton?
A millinewton equals one thousandth of a newton.
Common contexts: precision instruments, biomechanics.
How to Convert Dynes to Nanonewtons
To convert dynes to nanonewtons, multiply by 10,000. Both units operate in the small-force regime relevant to biophysics, surface mechanics, and nanoscale instrumentation. The factor is exact, arising from the definitions of the two units relative to the newton.
Conversion Formula
- Dynes to nanonewtons: nN = dyn × 10,000
- Nanonewtons to dynes: dyn = nN ÷ 10,000
- Scientific notation: 1 dyn = 1 × 10⁴ nN
The four-order-of-magnitude factor reflects the gap between CGS-era macroforce thinking and nanoscale modern instrumentation. Even an "average" dyne reading translates to tens of thousands of nanonewtons.

Understanding the Units
What Is a Dyne?
The dyne (symbol: dyn) is the CGS unit of force, equal to one gram-centimetre per second squared — or 10⁻⁵ N. Despite its modest size by everyday standards, it is enormous compared to molecular-scale forces, which is why bridging to nanonewtons is often needed when comparing legacy and modern data.
What Is a Nanonewton?
The nanonewton (symbol: nN) is one billionth of a newton (10⁻⁹ N). It is the natural unit for cellular-scale biophysics: cell-substrate adhesion (10–1,000 nN), AFM imaging forces (~1–100 nN), nanoindentation hardness probes, and single-protein conformational forces in the higher end. Below the nanonewton lies the piconewton (10⁻¹² N), used for individual molecular motors.
The Sub-Newton Hierarchy
Force units below the newton step down by factors of 1,000: 1 N = 10³ mN = 10⁶ µN = 10⁹ nN = 10¹² pN. The dyne sits between the millinewton and micronewton (1 dyn = 10 µN = 0.01 mN). Choosing the right unit depends on instrument resolution and the audience: scientific papers prefer SI prefixes; legacy CGS reports use dynes.
Nanonewtons in Biophysics and AFM
| Source of Force | Approximate Force (nN) | In Dynes |
|---|---|---|
| Single titin protein unfolding | ~150–300 nN (peak) | ~0.015–0.03 dyn |
| AFM cantilever, contact mode imaging | ~1–100 nN | ~10⁻⁴–10⁻² dyn |
| Cell-substrate adhesion (single fibroblast) | ~100–1,000 nN | ~0.01–0.1 dyn |
| Maximum stall force of myosin V | ~3 pN (= 0.003 nN) | ~3 × 10⁻⁷ dyn |
| Nanoindentation, polymer film testing | ~10,000–100,000 nN | ~1–10 dyn |
| Single antibody–antigen rupture | ~50–200 pN (= 0.05–0.2 nN) | ~5 × 10⁻⁶ dyn |

Brief History
The dyne was codified by the British Association for the Advancement of Science in 1873 as part of the CGS system. The SI prefix "nano" (from Greek nanos, "dwarf") was adopted in 1960 for factors of 10⁻⁹, and applied immediately to all SI units including the newton (named in 1948). The nanonewton therefore dates effectively from the 1960 SI overhaul.
The rise of atomic-force microscopy in the 1980s and 1990s, followed by single-molecule biophysics in the 2000s, established the nanonewton (and piconewton) as the working units of choice for cellular and molecular mechanics. CGS dynes survive only in legacy datasets and specific theoretical-physics conventions today.
