Round Trip Time (RTT) to Latency Calculator

Convert network RTT to end-user latency for different protocols. HTTP/1.1: 2×RTT for new connections. HTTP/2 with TLS 1.3: 1×RTT (0-RTT possible). QUIC (HTTP/3): 0-RTT on known hosts.

How to Use

Enter the values for the scenario you are assessing. Convert network RTT to end-user latency for different protocols. HTTP/1.1: 2×RTT for new connections. HTTP/2 with TLS 1.3: 1×RTT (0-RTT possible). QUIC (HTTP/3): 0-RTT on known hosts. Use the rtt to user latency result to inform your calculation.
