Kilograms per Second to Tonnes per Day (kg/s to t/day)
1 kilogram per second (kg/s) = 86.4 tonnes per day (t/day). 1 t/day = 0.01157407407 kg/s. Example: 15 kg/s = 15 × 86.4 = 1296 t/day.

How to Convert Kilogram per Second to Tonne per Day
- 1 kg/s = 86.4 t/day
- 1 t/day = 0.01157407407 kg/s
- Example: convert 15 kg/s to t/day: 15 kg/s = 15 × 86.4 t/day = 1296 t/day
Formula
t/day = kg/s × 86.4
Derivation from SI units:
- Mass per unit time: kg/s.
- 1 t/day = 1000/86,400 kg/s.
Both units are defined exactly, so the factor is exact. Kilogram per Second definition: kilogram per second; Tonne per Day definition: tonne per day.
Worked examples
- A reading of 1 kg/s converts to 86.4 t/day.
1 kg/s × 86.4 = 86.4 t/day - A value of 10 kg/s is 864 t/day.
10 kg/s × 86.4 = 864 t/day

Where it's used
Kilograms per Second are used for mass and energy balances, while tonnes per day appear in chemical and fertiliser plant capacity. Both measure mass flow rate ṁ, so the conversion is a fixed factor.

Frequently asked questions
How many tonnes per day are in 1 kilogram per second?
1 kg/s = 86.4 t/day.
How do I convert kilograms per second to tonnes per day?
Multiply the value in kg/s by 86.4. For example, 15 kg/s × 86.4 = 1296 t/day.
Is the kg/s to t/day conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
